1. HP SERIES POWER DETECTORS

1.1. INTRODUCTION

The Gentec-EO HP Series power detector family includes HP100A-3KW-HE, HP100A-4KW-HE, HP60A-10KW-GD and HP100A-12KW-HD.

- The HP100A-3KW-HE detector has dimensions of 127 mm x 127 mm and an aperture of 100 mm.

- The HP100A-4KW-HE detector has dimensions of 127 mm x 127 mm and an aperture of 100 mm.

- The HP60A-10kW-GD detector has dimensions of 127 mm x 127 mm and an aperture of 60 mm.

- The HP100A-12KW-HD detector has dimensions of 127 mm x 127 mm and an aperture of 100 mm.

- The high power surface absorber sensors are designed for use at high average power densities.

The HP detectors can measure between

- 100 W and 3 KW of average power for HP100A-3KW-HE,

- 100 W and 4 KW of average power for HP100A-4KW-HE,

- 300 W and 10 KW of average power for HP60A-10KW-GD.

- 300 Wand 12 KW of average power for HP100A-12KW-HD.

*For lower power, consult Gentec-eo The HP-D0 detectors are supplied with a 180 cm length flexible cable with output connection options

of a DB-15 "intelligent" male connector.

NOTE: To eliminate possible damage, do not carry the detector using the connector cable. Some HP detectors are supplied with a stand (optional). For cases where Gentec-EO’s monitors don’t automatically read the wavelength correction factor,

you can use your detector’s “Personal wavelength correctionTM Certificate” to adjust the power you

read to a power corrected for a particular wavelength. Call your nearest Gentec-EO distributor to replace the sensor disk and/or to recalibrate the head.

For Gentec-EO’s nearest office contact information, see p. ii, Contacting Gentec Electro-Optics Inc.

1.2. POWER DETECTOR CONNECTORS

1.2.1. DB-15 “intelligent” connector

The DB-15 male "intelligent" connector contains an EEPROM (Electrically Erasable Programmable Read-Only Memory) with different information related to the HP Series detector head in use: detector model, calibration sensitivity, applicable scales and wavelength correction factor for up to 20 wavelengths.

This connector, available in the HP, allows the P-LINK, S-Link, SOLO 2, UNO, TUNER, MAESTRO (detector model, calibration sensitivity, scale and wavelength correction factor) monitors to adjust their characteristics automatically to the power sensor being connected. No calibration procedure is required when installing the power heads, allowing for faster set-up.

The DB-15 connector pin-out is composed of (see Fig. 1-1):

1.2.2. USB connector

The USB connector allows using the HP on a PC. The PC interface, PC-HP, features statistical

calculation, graphics displays and data logging options. It also gives real time measurement of

the cooling flow rate and temperature.

A standard USB cable of 5 meters is supplied with the HP. If a longer cable is required, please

contact Gentec-EO for more information.

A USB power adapter (201221) can be ordered with the required AC plug ; USA (201222), UK

(201223), European (201224) and Australian (201225).

1.2.3. Cooling water

The fluid used to cool the HP must be clean water.

Water Fittings and tubing :

- The HP is equipped with 3/8’’ (OD) tube push to connect fittings.

- It must be used with plastic pressure tube systems (like PE tubes). The fittings is not compatible with copper or stainless steel tubes.

- The metric version of the HP is supplied with an adapter kit (201993) for 10 mm tube (OD).

 The kit contains two push to connect 3/8’’ to 10 mm tube adapters and two 3/8’’

coupling tube stems.

 The coupling stem is inserted between the HP and the adapter.  Please note that the tube size is written on the adapter output (10 or 3/8).

Water Quality:

- The HP series cooling fluid must be water, do not use glycol or other additive that changes the coolant’s heat capacity.

- Use filtered (< 10µm) water to avoid any residue. Gentec-eo can provide an external water filter (202149) if water quality is an issue.

- Distilled water can be used, but it is not recommended to use highly deionized ultra-pure water because the water cavity is not completely inert.

- If an algaecide must be used in the chiller, we recommended Optishield Plus or equivalent.

- If chloride is present in the system, the concentration should not exceed 25 PPM and the PH maintained at 7.0.

Water temperature:

- The cooling water can be between 15 and 25°C but must always remains above the dew point.

- The ideal set point is 20.0°C, where the HP is calibrated.

- Water temperature stability is very important since variations (1 to 60 seconds) in the temperature can be interpreted as laser power fluctuation.

- Regulate the temperature with a chiller or a re-circulator.

- The water temperature can be monitored with the PC interface PC-HP.

Water Flow rate:

- Flow rate stability is very important since the measured power is directly proportional to the flow. Variation (1 to 60 seconds) in the flow rate can be interpreted as laser power fluctuation.

- The flow rate must be adjusted with a valve. A lower flow rate causes a slower response while increasing the signal to noise ratio. A higher flow rate causes a faster response, reducing signal to noise ratio.

- The water flow rate can be monitored with the PC interface PC-HP.

Note: All these parameters should remain in the range stated in the specifications.

2 OPERATING INSTRUCTIONS

- In order to ensure a long lifetime of accurate measurements, it is recommended that HP is held within the following ambient conditions:

- Storage environment temperature: 10 to 65°C, RH < 90%

- Operating environment temperature: 15 to 28ºC, RH < 80%.

It is possible to store and operate your Gentec-EO UP wattmeter beyond this range. For any

specific requirement, please contact your local Gentec-EO representative.

- Connect the detecting head (equipped with 3/8’’ tube push to connect fittings) to a water cooling supply.

NOTE: Ensure that the connection is water-tight by cutting the end of the tube perpendicular to the tubing. The portion of the outer tubing wall that slips into the fitting must not be deformed or damaged.

 To connect the detector head fittings to the water supply tubing: push the tubing

into the fitting until it comes to the end.

 The direction of flow through the head is very important. The measured

power will be negative if the direction is inverted.

 Once you have connected the fittings, check them for leaks. If you find a leak,

check to see if the tubes are pushed in far enough and that the tubing has not been damaged.

 To disconnect the detector head fittings, remove the water pressure and drain

the water from the tubing. Press the black part of the fitting and pull out the tubing.

NOTE: Water will usually remain in the detector head after it is disconnected. It is possible to remove it by blowing it out, but be careful not to blow the water on yourself or on the detector aperture. Dry the detector body and absorber off before storing it.

 Be sure that flow rates satisfy the minimum values, as indicated on the

specifications page.

 Time variations in water flow rates or water temperature will cause

corresponding oscillations in measurements.

 The water temperature and flow rate can be monitored with the PC

interface PC-HP.

- For the most accurate measurements, center the beam on the sensor face. The beam diameter on the sensor should ideally be the same size as the beam diameter of the original calibration, which corresponds to >98% encircled power centered on 70-90% of the sensor’s surface (this complies with the International Electrotechnical Commission standard #1040: "Power and Energy Measuring Detector..."). Refer to the calibration certificate for the exact calibration beam diameter.

HP is used simultaneously).

WARNING: Be careful not to exceed the maximum levels and densities stated in the

specifications, refer to section 4, Damage to the optical absorber material, for detailed informations.

Strong fluctuations in the zero level are usually caused by one of the following :

1) Rapid fluctuations in water temperature.

2) Rapid fluctuations in the water flow rate.

WITH ANY GENTEC-EO MONITOR

- To operate the HP detector, connect the detector head to the input socket of the monitor (see the monitor’s instruction manual).

- If a extension cable is used to connect the HP to a monitor, the HP must be powered from a PC via the USB port or with an optional USB power adapter.

- Before taking measurements, block off the detector head to prevent it from sensing heat from random sources. To obtain an accurate reading, the monitors must be zero adjusted.

- Allow the detector head to thermally stabilize before making any measurements. Let the signal stabilize for a few seconds before adjusting the offset. Refer to the monitor’s operating instructions for further details.

2.1 WITHOUT A GENTEC-EO MONITOR

- The HP must be powered from a PC via the USB port or with an optional USB power adapter.

- Connect the power head to a precision microvoltmeter, or data acquisition system, with a load impedance that is >100 k. Because of the very low voltages at lower power levels for some of these detectors, analog or digital filtration may be required to remove ambient electromagnetic interference.

- Put the power head into the laser beam path (the laser beam must be contained within the sensor area) for about a minute.

- Switch on the voltmeter and adjust its voltage range to the range required for the measurement. To determine the voltage range to be measured, refer to the detector head specifications:

- Block off any laser radiation to the detector.

- Wait until the signal has stabilized, then measure the zero level voltage offset from the detector.

- Apply the laser beam to the power head.

- Wait until the signal has stabilized (between one to three minutes for optimum measurements), then measure the voltage output from the detector .

Vout = (expected power) x (sensitivity of power detector)

Page 12

Version 2.2

- The measured power is calculated as follows:

Measured power [W] = (output voltage [V] - zero level voltage [V]) / sensitivity [V/W] = 1000 x (Vout [mV] - Vzero level [mV]) / sensitivity [mV/W]

2.2 WITH PC-HP

This section describes in detail the first group of menus essential to the PC-HP operation. The display menu lets you view the status and your measurement in various ways. Use the settings menu during setup to set the best parameters for the measurement task at hand. It provides the flexibility to accommodate a wide variety of measurement conditions.

The water temperature and flow rate are displayed in real-time at the bottom of the interface

2.2.2 PC-HP Shortcut Buttons

To access certain features with a single click instead of having to enter the menus, PC-HP has 8 shortcut buttons on its main window. From left to right, those buttons access: Zero Offset,

Display - Histogram, Display - Tuning Needle, Display - Statistics, Display - Status, Settings Data Sampling, Ctrl - Communication - Connect, Ctrl - Communication-Disconnect.

FIG. 2-4 PC-HP SHORTCUT BUTTONS

2.2.2.1 Zero

This feature resets the zero reading level to compensate for electronic offsets in the HP and thermal noise in the environment of the detector. When the HP receives the associated command, it subtracts the power reading on all its internal hardware scales. Subsequent measurements will be relative to this zero power level. Use this function once your power meter has achieved thermal equilibrium to ensure accurate measurements.

For instructions on the proper way to adjust the offset to zero your detector see section 2, Operatings Instructions.

Page 16

2.2.3.3 Display - Status

Version 2.2

FIG. 2-9 PC-HP SETTINGS WINDOW

The Settings window displays various settings.

2.2.3.3.1 Status - Wavelength

Use The Wavelength menu to select the power wavelength at which the detector is to be used. It applies a correction to adjust for the variation in responsivity at different wavelengths. When a new thermal detector is plugged in, the calibration wavelength is the default selection.

PC-HP only allows you to choose values that fall within the detector’s range. If you select or enter a value that is not valid, a menu pops up to signal the error and PC-HP automatically selects the default value. That is the wavelength used for calibration at Gentec-EO during manufacture or subsequent service.

The HP automatically recognizes every power detector, for accurate auto-calibration. More importantly, it takes advantage of our Personal wavelength correction™: it reads the memory in the Smart Interface connector to provide a wavelength correction based on spectral data measured from that specific detector. Your measurements across the band have never been this precise and easy.

When working at a wavelength not available in the Wavelength menu, use the custom option. If you choose custom, a dialog box appears where you can enter a wavelength. The wavelength you enter must be within the range of valid wavelengths. The HP interpolates a wavelength correction factor using the pre-programmed data in the detector’s EEPROM.

2.2.3.3.2 Status - Corrections

The user can apply one multiplier and one offset to the detector reading. Correction factors are most useful when sampling a percentage of a powerful laser beam or correcting for absorption along an optical chain. The Status window displays the values of correction factors that are being applied to the measurements. To activate the correction factor, select Status in the Display Menu and then select Multiplier or Offset. A dialog box opens where you enter the correction value in percentage or as an absolute value. This number will then multiply, or add to the actual measured value to calculate the corrected value. PC-HP will then display the corrected value.

Note that the Statistics are computed for the corrected values only. To disable the correction factor, do a Display – Status – 1 & 0.

2.2.3.3.3 Status - Anticipation

Thermal power detectors are inherently slow. The HP uses an algorithm to significantly

accelerate the response. This is called “anticipation”. By default, this option is enabled. The

reasons for disabling the anticipation are to slow down the response and to lower the noise level.

2.2.5.1 Data Sampling

The Data Sampling parameters are used for calculating the statistics(see section 2.2.4) and for data acquisition(see section 2.2.6.2). PC-HP uses default sampling parameters unless you set them yourself. You can set PC-HP either to calculate the statistics for a single sample and stop or to repeat continuously. Take data for a few seconds or a few weeks. You have the flexibility to handle any application, from analyzing a single short pulse with high resolution to sampling performance over a period of months. The statistical parameters that are calculated are listed in Table 2.2.

Figure 2.9 shows the window for setting the data sampling parameters. Table 2.2 describes the parameters. When finished setting them, click save to activate the parameters.

2.2.6.1 Ctrl - Communication

The communication item is mostly used to Connect to the HP after starting PC-HP. To use the COM port for another application without closing PC-HP, click Ctrl / Communication / Disconnect.

2.2.6.2 Ctrl - Acquire Data

This item is used to save raw data (only), statistics (only), or both raw data and statistics in an output file. When you select Start Saving Raw Data, a dialog box appears. Type in the filename that you choose, then select save. PC-HP begins storing raw data according to your Data Sampling settings (see section 5.2.2). If you will be putting the information into a spreadsheet, use the Save Both option. All the raw data will be at the top of the file, while all the statistical information will be at the bottom of each period. The Stop Saving command stops the data recording but the HP will continue to provide measurements to the display.

2.2.6.3 Ctrl - Statistics

-Select Start to start collecting statistics(when stopped) or to restart them when already in

progress.

-Select Stop to freeze the statistics.

2.2.7 Help - About

This item is helpful to check the software version (About Application…). If you should need help or additional information on the HP or any Gentec-EO products, do not hesitate to contact us. We will be glad to help you.

2.2.8 USB driver Installation

Plug the HP into a USB port on the PC. If the PC supports USB 1.1, Windows detects the new device and prompts you for the software drivers. A window will open that says Found New Hardware – USB Device and after several seconds to a minute, the Found New Hardware Wizard will appear. Insert the GENTEC-EO Software CD-ROM if not done already.

For Windows 2000, XP or Vista: Cancel the wizard and execute the Auto installer “USB driver

installer-r2” in the USB Driver folder from the CD-ROM. Please note that old monitors without the (R2) at the end of the product name need a different

USB drivers which are available on our web site. They do not support Windows VISTA, unless noted on the web site.

At the end of this process, a new serial COM port will be added to the list of communication ports. It may be used as any other serial port. You will need to know the COM port number to set up the serial connection to the HP.

2.2.9 Verify COM Port

To verify the USB installation and find the COM port number click: Start → Settings → Control Panel → System → Device Manager

(Instructions may vary a bit by operating system and version. For Win2000/XP there is an additional step (is there an extra step – if so what is it – or an extra click?- on my system it’s an extra click) between Control Panel and System.)

Scroll down to Ports (COM & LPT) and double click that line. One of the options should be USB-to-Serial Port (COM#) Note the COM port number. You need it for the next step.

3 SAFETY OPERATION NOTES

3.1.1 Diffusive surfaces

When using the HP be aware of the diffused back reflection ~ 10-15%. As on any diffusive surface, the light on the sensor coating is scattered more or less uniformly

as a Lambertian diffuser.

3.1.2 Detector temperature

Detectors can become hot enough during usage to cause burns.

4 DAMAGE TO THE OPTICAL ABSORBER MATERIAL

The HP series are high power meters that can measure up to 12KW. The beam diameter should always be as large as possible to avoid damage to the absorber. We are recommending between 50% and 80% of the head aperture area, e.g. 7 cm in diameter for the HP100A, 2.5 cm in diameter for the HP60A-10KW-GD.

The damage threshold is decreasing with the laser beam power. The following table calculates the

diameter corresponding to the damage threshold for a Gaussian beam profile. The “minimum 1/e²

beam diameter” is calculated to obtain a peak intensity 50% lower than the damage threshold and

should be considered as the “safe” minimum diameter. If there are “hot spots” in the beam profile,

they must be considered in the calculation of the peak intensity.

Peak Intensity. For Gaussian beam profile, the peak intensity is twice the beam power. Diameter of a circle corresponding to 86% of the entire beam power. Including a security factor of 50%
