SECTION TWO: DESCRIPTION

In this section:

• Unpacking (p. 2-2)

• System description (p. 2-3)

• Maintenance (p. 2-9)

• Replacement parts (p. 2-10)

WaveMaster™ provides a simple and quick method of determining
the wavelength of lasers in the 380 to 1095 nm range, to an accuracy
of 0.01 nm or better. It can measure CW, pulsed, and single shot
lasers. There are four available units of measurement:

• Wavelength in air (nm, at standard temperature and pressure)

• Wavelength in vacuum (nm)

• Wave number in vacuum (cm

-1

)

Description

• Frequency (GHz)

WaveMaster has an internal calibration system based on precisely
known wavelengths of neon spectral lines. Periodic recalibration is
performed automatically to ensure measurement accuracy.

Laser input to the instrument is by means of a standard ST type fiber
optic connector, which means that WaveMaster can be situated in
any convenient position and does not require alignment with the
laser source.

An input sensor with a 2-meter fiber cable is supplied for capturing
or sampling of the beam, but other inputs having a suitable
connector may be provided by the user. The maximum input to this
front panel connector should be limited to 100 mW so as to avoid
internal damage.

A front panel intensity meter assists in aligning the sensor and in
establishing a suitable signal strength level for measurement, which
can be adjusted by means of the built in front panel attenuator.

The measured value is displayed in large, easily read characters on
a LCD panel, which also carries information on the status of the
instrument. The display contrast may be set by the user to suit the
ambient conditions and back lighting is available as required.

Remote operation is accommodated by means of an RS-232 or USB
serial port.

Specifications for WaveMaster are listed in “Appendix B: Specifica­tions” (p. B-1).

Description

System Description

Display Unit

Front Panel Controls

The WaveMaster equipment consists of three units:

• The display unit

• The sensor

• The power supply

Figure 2-1. Front Panel

Here is a description of the various controls and displays:

ON/OFF: Pressing this button toggles the power to the instrument.

When switching ON, the yellow Pulse Received indicator will light
and stay lit until characters appear on the display. This takes a few
seconds. When switching OFF, the message “Powering Off” appears
on the display for a few seconds while the instrument shuts down.

The current state of the instrument settings is saved during shut­down and reinstated at the next start-up.

BACKLIGHT: Pressing this button toggles the display back light

and meter lamp on and off.

CONTRAST: These two buttons allow the user to set

a display contrast level appropriate to the ambient lighting condi­tions. Holding the buttons down causes the contrast to change
continuously (between limits).

2 - 3

WaveMaster User Manual

AUTOCAL: Pressing this button toggles the internal automatic

calibration process on and off. The current state is shown in the
“Autocal” box on the display above the button. In normal circum­stances, AUTOCAL should be left ON to ensure measurement accu­racy. Turning AUTOCAL off and then on forces an immediate
internal calibration.

UNITS: Pressing this button cycles through the four available units:

nm air, nm vacuum, wavenumber (cm-1), and frequency (GHz). The
current unit selected is shown to the right of the measured value on
the display.

MODE: Pressing this button cycles through the three modes: CW,

CW Av, and Pulse. The mode in use is displayed in the “Mode” box
on the display above the button.

PULSE RECEIVED: Apart from being lit during power up—refer

to “ON/OFF” (p. 2-3)—this indicator is only active when the instru­ment is in pulse mode. In this mode, it flashes every time a valid
pulse measurement is made.

INPUT: This is a combined fiber optic input connector and attenu-

ator. The connector accepts the fiber optic cable that is part of the
sensor assembly. Turning the attenuator clockwise (+) increases the
signal delivered to the instrument, and turning the attenuator coun­terclockwise (-) decreases the signal.

NOTICE!

The connector is an ST type and only cables terminated with this
type of coupling must be used. Attempts to use other connectors
may cause damage. Additionally, to avoid internal damage, the
maximum input power to the instrument front panel attenuator
must not exceed 100 mW.

INTENSITY: This indicates the signal strength as seen by the

instrument on a meter scale with red and green zones. It is not a
measurement of laser power.

The sensor and input attenuator should be adjusted so that the meter
needle is in the green scale area and preferably towards the
right-hand side. The red region to the right of the scale indicates
danger of signal overload. The red region to the left of the scale indi­cates too low a signal, although a valid reading may still be
displayed.

Description

Front Panel Display The LCD presents all the information about the measurement and

operation status of the instrument. Its contrast can be controlled
between limits to suit the ambient lighting conditions. Additionally,
it can be backlit, together with the intensity meter, to further improve
visibility.

The upper part of the screen is used principally for the display of
measurements in the selected units, with a blank display indicating
that no valid reading is available or possible. The selected unit is
indicated to the right of the numerical part of the display. The
number format is shown in the following table.

In CW mode the display is updated at 3 Hz with the last reading

taken.

In CW Av mode, the display is updated at 3 Hz with an average of

the last 10 readings taken by the instrument. When the signal is
removed, the last reading is displayed for 3 seconds until the display
blanks.

In PULSE mode, when a valid pulse is detected by WaveMaster, the

display will show the reading for that pulse for 15 seconds or until
another valid pulse or error condition is detected. Note that the Pulse
Received light also flashes when a valid pulse is detected.

There are circumstances when a valid measurement cannot be
displayed or such a display is not appropriate. In these cases a text
message is presented in the measurement area. All such messages
that can be generated by WaveMaster and the situations in which
they are produced are discussed, below.

INITIALIZING: Appears immediately after power on while the

internal hardware and software initialization takes place.

AUTOCAL: An internal wavelength calibration is taking place.
AUTORANGING: Internal adjustments are being made to accom-

modate the input signal level.

SATURATED: The input signal level is too high and must be

reduced by using the front panel attenuator or other means.

2 - 5

WaveMaster User Manual

MULTI-LINE: More than one wavelength is present in the input

signal. Frequently this is the case with diode lasers.

POWERING OFF: The last message before the instrument

switches off. It is usually a result of operating the OFF switch or
automatic power-down (when enabled) in battery operation. Irre­coverable error situations can arise that result in automatic power off
action being taken.

AUTOCAL FAIL: The internal wavelength calibration has failed.

The instrument continues operating after this occurs and will shortly
attempt a further calibration cycle. If it occurs as part of the
power-on sequence, automatic power down follows.

FATAL ERROR: A serious irrecoverable internal error has been

detected. Automatic power down follows. If it is a transient fault,
then powering back on should be possible.

MEM FAILURE: A serious internal memory fault has been

detected. This can only be rectified by return for servicing.

FACTORY MODE: A serious internal error has been detected.

This can only be rectified by return for servicing.

The lower part of the display contains information about the state of
the instrument.

REMOTE/LOCAL: Indicates whether the instrument is being

controlled from a separate computer (Remote) or from the front
panel (Local). In remote mode, the AUTOCAL, UNITS, and MODE
buttons are inoperative.

AUTOCAL: This box is positioned above the AUTOCAL button

and indicates whether autocalibration is on or off. In the OFF state,
the legend flashes to indicate that this non-preferred state (when
quoted accuracy cannot be guaranteed) has been selected.

MODE: This box is positioned above the MODE button and indi-

cates which of the three modes (CW, CW Av, or PULSE) is currently
selected.

The items on the rear panel and their respective functions are
described, below.

12 VDC Power In Connector: Only the power supply shipped with

the WaveMaster should be connected to the instrument. The power
supply comes with mains plugs for most countries, and can be
connected to voltages from 90 to 240 VAC.

NOTICE!

Using a power supply other than the one shipped with the
product may cause the instrument to fail.

USB Type A Connector
RS-232 Connector: This is a female 9-pin D connector. The pin out

Sensor

An input sensor—supplied as part of the WaveMaster
system—provides a versatile and convenient way of collecting laser
energy for measurement. The sensor may be attached to a standard
mounting post and a post, post-holder, and base are also supplied.

There is a switch on the top of the sensor which offers two input
collection options: In one position the sensor has a wide field of
view but reduced sensitivity. The other position provides maximum
sensitivity but reduced collection angle. The sensor is provided with
a captive fiber-optic cable—two meters in length—for connection to
the WaveMaster.

Figure 2-3. Exploded and Sectioned View of Laser Input Sensor Front End

The front end of the sensor is designed to provide as much flexibility
in the method of use as possible. The nosepiece (1) contains an
uncoated thin glass plate at 45 degrees to the sensor axis. This allows
the sensor to be inserted at 90 degrees to a beam to collect a few
percent of the radiation, while allowing the remainder of the radia­tion to pass through. The nosepiece screws into the front part of the
sensor assembly (3) and the orientation of the 45-degree plate can be
set by means of the lock ring (2). There is a hole in the front of the
nosepiece which may be used as an axial input for a laser beam. If
this is used, care must be taken to ensure that the energy reflected
from the glass plate is absorbed safely. The nosepiece can be
completely removed for direct axial input

The front part of the sensor (3) screws onto the main sensor body (6)
and may be used to hold a 12.7 mm filter or diffuser (4 - not
supplied) in place. Item (5) is a plastic retaining washer.

The uncoated glass plate used for beam splitting in the sensor nose
unit may not preserve the wave front quality in certain applications,
although the signal passed to the WaveMaster is of acceptable
quality for its measurement. If continuous sampling of a signal in an
optical set up is required, then the signal to the WaveMaster sensor
should be extracted using appropriate laser quality beam splitting
optics.

2 - 8

Power Supply

Description

As an alternative to using the sensor, the user may supply their own
input, provided it is a fiber terminated in a standard ST connector for
connection to the front panel of the instrument.

NOTICE!

The maximum safe input (to prevent damage) must be limited to
100 mW, although this level is far too high for measurement.

NOTICE!

The switch-mode mains power supply provided as part of the
WaveMaster system is the only power supply that is to be used
to provide external power.

Maintenance

The power supply requires assembly by sliding the mains plug
adapter appropriate to the country of use onto the power supply
body. It is not recommended that the adapter is changed frequently,
but this interchangeability can be convenient if WaveMaster is to be
operated in different countries.

The output lead from the power supply is connected to the socket on
the rear panel of the instrument.

NOTICE!

The display and window should be cleaned using only a cloth
moistened with water. Do not use chemicals or cleaners. The
WaveMaster should not be sprayed with anything.

WaveMaster contains no user-serviceable parts. Under no circum­stances should the instrument case be opened. WaveMaster contains
delicate optical components that have been carefully aligned.

WaveMaster includes an internal calibration system, which the
system uses to self-calibrate against the output spectrum of a neon
source. During this calibration, WaveMaster measures the wave-

2 - 9

WaveMaster User Manual

length of 13 separate neon emission lines distributed across its
measurement range, and compares measured values with known,
published values. WaveMaster automatically recalibrates itself if
these measurements fall outside tolerance.

WaveMaster performs this internal calibration when first powered
up and at intervals of approximately 1 minute thereafter.

Due to its automatic internal calibration against atomic spectral
lines, WaveMaster does not require additional calibration during
manufacture or during service life. WaveMaster should be consid­ered permanently calibrated.

The nose unit accepts ½-inch diameter filters of various thick­nesses—item 4 in Figure 2-3 (p. 2-8). The thread on the front of the
nose unit is 0.535 inch x 40 UNC—item 3 in Figure 2-3 (p. 2-8).

The fiber optic cable on the sensor can be extended using readily
available standard cables that are terminated with an ST connector
on each end. They should be attached to the sensor ST connector
using a female-female adapter. These items are available from many
general distributors as standard fiber patch cords intended for
networking/communications applications. A multi-mode 62.5/125
micron fiber is recommended. The very high input sensitivity of
WaveMaster ensures there are no problems with attenuation by the
cable, even if very long lengths are used.

SECTION THREE: OPERATION

In this section:

• Making a measurement (this page)

• Remote operation (p. 3-2)

• Getting the best from WaveMaster (p. 3-10)

Operation

Making a Measurement

Once the instrument has been set up, press the POWER button. The
instrument will now cycle through its self-test sequence. If this does
not occur, refer to “Section Four: Frequently Asked Questions”
(p. 4-1) for advice on possible easily-rectified error conditions.
After approximately five seconds, the instrument will enter its auto­calibration mode. Once the AUTOCAL message has cleared from
the display area, WaveMaster is ready to take measurements. The
best results, as with any high-accuracy measurement instrument, are
achieved after a suitable warm up period. System settings at the last
power off will have been remembered by the instrument and will
now be in effect. (Even though autocalibration may have been
disabled, WaveMaster will always perform an initial calibration as
part of its power up sequence. Also, it will always power up ready
for local control.)

It is now necessary to adjust the level of input signal to the instru­ment. This is achieved using the messages and reading on the
display in conjunction with the indication on the intensity meter. The
aim is to have the intensity indication well into the right-hand side
of the green sector of the scale.

If the display screen is currently blank and the intensity meter indi­cating in the red region at the left-hand of the scale, more input
signal is required. It is worth first adjusting the front panel attenuator
in a clockwise direction (+) to see if this achieves the necessary
increase in signal. If not, then adjust the alignment of the sensor with
the laser beam. The acceptance angle of the sensor is quite small and
care must be taken in the alignment to ensure that the laser radiation
is focused onto the sensor fiber-optic cable.

Note that while adjustments to the input signal level are being
carried out, the message AUTORANGING may appear on the
display screen. This occurs as the instrument responds to significant
input level changes by automatically making internal adjustments.

3 - 1

WaveMaster User Manual

The intensity meter indicates the absolute input signal level and
takes account of any internal ranging carried out. Internal ranging
occurs in the CW and CW Av mode, but not in Pulse mode.

If the display screen currently shows the message SATURATED and
the intensity meter is in the red region at the right-hand of the scale,
less input signal is required. Adjust the front panel attenuator in a
counter-clockwise direction (-) to decrease input signal. If this does
not reduce the signal level far enough then the alignment of the
sensor with the laser beam may be altered to sample less of the signal
or additional attenuation placed between the signal being measured
and the sensor.

When adjusted for the correct intensity level, the wavelength
reading should be displayed on the screen. It will be in the
currently-selected unit chosen from nm in “air” (at standard labora­tory temperature and pressure (STP)), nm vacuum calculated by
conversion from STP, wave number (cm-1), or frequency (GHz). A
valid measurement can be achieved over a wide range of front panel
attenuator settings and is not influenced by the input signal level.
The preferred signal level, however, is with the intensity reading in
the right-hand part of the green region of the scale.

Remote Operation

If the display shows MULTI-LINE, the input signal is composed of
multiple wavelengths or is too wide in bandwidth. Many diode lasers
will exhibit this until they thermally stabilize. By decreasing the
input signal level using the front panel attenuator, it may be possible
to get wavelength readings by decreasing the very adjacent spectral
lines below the detection level of the instrument. Such a technique
will not work with genuinely polychromatic sources.

Further advice on making measurements can be found in “Getting
the Best from WaveMaster” (p. 3-10) and “Section Four: Frequently
Asked Questions” (p. 4-1).

By connecting the WaveMaster to an external computer (through
either of the interfaces), measurements and other instrument settings
can be read, stored, and controlled. The WaveMaster also features a
mode for automatic periodic output of wavelength data and allows
the computer to be used as a logging device.

The WaveMaster offers a choice of RS-232 and USB computer
interfaces for remote operation. Once data has been sent on an inter­face, only that interface can be used to control the instrument. It is
necessary to power off to effect a change of controlling interface.

Operation

Introduction

Computer interface features:

1. WaveMaster can be treated as a wavelength transducer.

2. The command set is the same for both RS-232 and USB hard­ware interfaces.

3. Commands are insensitive to case (in this document, UPPER
CASE is used throughout).

4. Commands that take parameters ignore unnecessary white
space characters.

5. Multiple commands can be sent on a single line, separated by
the semicolon (;) character.

6. Only one of the RS-232 or USB interfaces can be active at any
time and is automatically selected after the data is received
from the host controller. If the type of interface is changed, the
instrument must be powered off and back on.

Unless stated otherwise, values given are in decimal unless the
number is of the form 0xdd, which is used for bit patterns more natu­rally expressed in hexadecimal. The input and output of such values
do not use the 0x characters. Single-bit values in byte type values
(that is, status bytes) are active high (=1) unless otherwise indicated.

WaveMaster uses the CTS & RTS hardware flow control facilities.
The above assignment is designed to be compatible with other
Coherent instruments.

A straight-through (not null modem) connection is needed when
connected to a serial port.

If a three-wire interface is more convenient, it is essential that pins
7 and 8 (CTS/RTS signals) are wired together at the WaveMaster
end of the connecting cable (this is most readily achieved inside the
connector).

USB Hardware Parameters

USB (Universal Serial Bus) is an industry standard that defines the
cables, connectors, and protocols used for connection, communica­tion, and power supplies between computers and electronic devices.

Communication with the Wavemaster USB can be made via a
terminal emulator program.

Operation

Commands Overview

The commands offered are the same whether control is through
RS-232 or USB.

In WaveMaster, all commands are sequential. The IEE488.2
commands provided for synchronization are recognized in the
implementation but have no effect on the operation. When using
RS-232 it is not possible to generate a Service Request signal. The
six commands used to configure or interrogate for a Service
Request-related function have no effect when used on RS-232; the
value returned will reflect any values sent or its default state.

Each command sent with any parameters is checked for correctness.
If in error, the command is not executed. The error is reported as a
numeric code in the error return message. The format and codes are
defined in “Error Formats” (p. 3-9) and Table 3-14 (p. 3-9). The user
is responsible for checking any error return made.

In the case of multiple commands on a line, all commands up to the
one in error are executed; the one in error and any remaining
commands are not executed. The error return additionally indicates
the numeric order of the command causing the error.

WaveMaster User Manual

Getting the Best from WaveMaster

WaveMaster is inherently capable of giving highly accurate and
repeatable results. This can be enhanced by a few elementary
precautions.

The fiber input should be fastened down to avoid any undue move­ment. Due to mode structure changes as the fiber is moved, ampli­tude variations may be seen if it is left so that its position can change.
Similarly, a very small change in wavelength (still well within the
accuracy specification) may be reported as the fiber is moved.

The best results, as with any high-accuracy measurement instru­ment, are achieved after a suitable warm up period. WaveMaster
requires approximately four hours to reach the best thermal stability;
however, measurements taken during this stabilization period are
still well within the accuracy specification.

The embedded optics are protected from vibration by the internal
mounting method used, but shocks adjacent to the WaveMaster
during measurements should be avoided.

Correct alignment of the sensor can assist in getting the optimum
level of signal for WaveMaster operation. The sensor allows for
entry of the input signal either along, or perpendicular to, the sensor
axis. The collar on the front can be rotated to align the pick off beam
splitter. It should be firmly tightened after setting to prevent any
further rotation. The nosepiece can be completely removed to allow
the maximum signal into the sensor along its axis. The lever on the
top of the sensor provides two options: narrow field of view/high
sensitivity, and wider field/lower sensitivity.

WaveMaster only requires a very small amount of laser energy to
make measurements. If plenty of energy is available, it may be
possible to place a diffuser in the sensor, which then makes align­ment much less critical. Alternatively, a rotating diffuser placed just
before the sensor can ease the alignment requirements and overcome
most of the fiber movement problems at the same time. However,
this is not suitable for pulsed laser measurements.

When running in a logging mode, the input on the intensity meter is
best adjusted to about mid-scale of what is expected to be the
maximum input signal level. Any amplitude variations to lower
signal levels are then automatically handled by the autoranging
feature and there is less chance of saturation occurring if the signal
increases. Note that many lasers exhibit quite wide amplitude varia­tions when run over an extended period.

When taking measurements of single shot pulse lasers, no triggering
of the WaveMaster is required. To ensure the event is captured, it is
recommended that the autocalibration be turned off immediately
prior to the event. The autocalibration should be reinstated after the
measurement to ensure continuing measurement accuracy. This

procedure avoids the instrument performing a periodic autocalibra­tion during a critical time for the user. Such a sequence can be
readily automated using the external communication facilities
provided.

Frequently Asked Questions

SECTION FOUR: FREQUENTLY ASKED QUESTIONS

FAQs listed in the following table provide information about the
internal operation of WaveMaster, and answer to the most
commonly-encountered problems.

Table 4-1. Frequently Asked Questions (Sheet 1 of 2)

Question Response

How does it work? The WaveMaster is a high diffraction order spectrometer. Wavelength is determined by

careful measurement of the separation between the diffracted orders. Much of the accu­racy and simplicity in use is achieved through software-implemented algorithms running
in the digital signal processor and conventional microprocessor in the instrument.

Why won't it power up? If WaveMaster is connected to the mains power unit and the yellow Pulse Received light

does not light, then the rear panel connector may not be making a good connection and
should be re-inserted. It is also possible that the mains psu has failed. This should give
12 VDC with the center of the connector positive.

Why does it power up but
powers off very shortly
afterwards?

What is autoranging? Autoranging is displayed when the instrument is making internal adjustments to its inte-

Why does it display
multi-line?

Why does the displayed
measurement flip between
values?

This does happen very occasionally. Restarting the instrument a second time should
clear the problem.

A persistent failure to start indicates a serious internal problem. The message that
appears briefly on the display provides some information about the cause of the failure.
The most likely cause is that the internal optics have become misaligned (probably
through undue shock) or the spectral calibration source has failed. The WaveMaster
should be returned to Coherent for servicing—refer to “Obtaining Service” (p. A-2).

Under a rare temporary fault condition, it is possible that the Power button on the front
panel will not operate. To power down the instrument, insert a non-metallic sensor or
adjustment tool into the small hole on the right-hand side of the case and press the
internal cut-out switch. If the problem recurs, contact Coherent for assistance—refer to
Table A-1 (p. A-2) for contact information.

The LCD has contrast that is sensitive to temperature. If the instrument has been taken
from a cold environment, the LCD contrast will need adjusting. This is done by using
the front panel controls to restore the displayed information.

gration period for the detector array. This ensures that a very wide dynamic range can be
offered to the user with the minimal need for intervention.

Due to the method of operation, WaveMaster has to work on the assumption that the
input is monochromatic. Laser diodes are particularly prone during periods of unstable
operation to generate distinct spectral content of very small amplitude very close to the
principal wavelength. Other laser sources may contain much more diversely-separated
wavelengths. In neither case can the WaveMaster algorithms resolve the spectral
content.

This is due to the behavior exhibited by the input source. Laser diodes are particularly
prone to this and WaveMaster has the accuracy to report such events. It has even been
observed on sophisticated frequency stabilized lasers when they have shown an odd
period of instability.

Why can’t I get RS-232
communications?

This may be caused by movement of the fiber input to WaveMaster. The fiber is
multi-mode, and the various modes propagating down the fiber interfere, thereby
causing intensity variations at the detector array. To overcome this, try to ensure that the
fiber cannot move, possibly by securing it with tape at one or more points. Even very
small movements can cause significant intensity changes.

This is due to multi-mode interference causing slight changes in the distribution of
energy at the detector array. The variations in wavelength are, however, very small and
well within the accuracy of the instrument.

The autocalibration may have been turned off. This is indicated by the flashing legend
in the Autocal box on the display. It could also be caused by the behavior exhibited by
the input source and WaveMaster has the accuracy and stability to track the wavelength
drift. Many apparently stable sources show drift characteristics when measured to the
accuracy that WaveMaster offers. Pulsed YAG laser drift as the crystal heats up is easily
observed, as are the rapid wavelength changes a diode laser makes.

The internal calibration is principally needed to overcome internal optical drift as a result
of thermal changes. Once the temperature of the instrument has stabilized, longer
periods are used to ensure that the WaveMaster spends as much time as possible making
input signal measurements and not calibrating itself. The user is unaware of the effect of
external ambient temperature changes through the adaptive autocalibration scheme
employed.

using CW or pulsed lasers with a high repetition rate, a continuous reading can be
displayed. In pulse mode with single shot operation, it is possible that the signal will
arrive while an internal calibration is taking place and thus an input measurement cannot
be made. By turning the autocalibration off before the event, such situations can be
avoided. The autocalibration should be reinstated after the measurement to ensure
continuing measurement accuracy. Note that turning autocalibration back on will cause
WaveMaster to recalibrate immediately, so that if the user wishes to force a recalibration,
it is only necessary to turn Autocal off and then on again.

Check that the receiving serial port has been set to the correct parameters as given in
“RS-232 Hardware Connection” (p. 3-3). A null modem is not required, all connections
being wired directly. The RTS/CTS lines are used, but can be unconnected at the host
end provided they are wired together at the WaveMaster connector.
