CHAPTER 1: Introduction
Figure 1-1 Millennia eV laser
The Spectra-Physics Millennia eV laser system is a diode-pumped, continuous-wave,
visible system. This laser system is a rugged, sealed unit designed for simple hands-free
operation.
The Millennia eV laser is smaller than competitive DPSS lasers of similar power. With
its intuitive GUI, automated command set, and superior design, the Millennia eV laser
is nearly maintenance free.
Millennia eV lasers have excellent near- and far-field beam pointing stability.
Some of the advantages of the Millennia eV laser are:
Reliable design and manufacture for high uptime
Lower cost of ownership
Excellent product value and low cost per watt
Robust manufacturing processes
The Millennia eV laser system was specifically designed for applications requiring a
high-quality beam, along with good mode quality in a cost-effective package. For a
more detailed description of the Millennia eV laser system, see
Description.”
System Control
During setup, a user-supplied computing device (typically a Windows-based personal
computer) must be connected to the Millennia eV laser head by means of either its
RS-232 or USB port to provide system control. Control software is provided on the
included USB memory stick for this purpose.

Environmental Control
Environmental Control
The Millennia eV laser system requires cooling fluid to remove heat and to stabilize the
temperature of various system components. A closed-loop chiller is used for this
purpose. The recirculating, temperature-controlled fluid flows to the laser head to
remove excess heat.

CHAPTER 2: Laser Safety
This chapter provides important information on laser safety and Spectra-Physics
recommends that the user read it carefully.
The Millennia eV laser system is a Class IV laser that emits laser radiation that can
permanently damage eyes and skin. This section contains information about these
hazards and offers suggestions on how to safeguard against them.
The Spectra-Physics Millennia eV laser is a
Class
IV — High-Power Laser whose beam is, by
definition, a safety and fire hazard. T ake precautions to
prevent accidental exposure to both direct and
reflected beams. Diffuse as well as specular beam
reflections can cause severe eye or skin damage.
Residual light at 1064
might also be present.
Safety Precautions for Class IV High-Power Lasers
nm and 8xx nm wave-lengths
Wear protective eyewear at all times. Eyewear selection depends on the wavelength
and intensity of the radiation, the conditions of use, and the visual function required.
Protective eyewear is available from suppliers listed in the Laser Focus World,
Lasers and Optronics, and Photonics Spectra buyer’s guides. Consult the ANSI and
ACGIH standards listed in
Maintain a high ambient light level in the laser operation area so that the eye’s pupil

remains constricted, reducing the possibility of retinal damage.
Avoid looking at the output beam; even diffuse reflections are hazardous.
Avoid blocking the output beam or its reflections with any part of the body.
Establish a controlled access area for laser operation. Limit access to personnel
trained in the principles of laser safety.
Enclose beam paths wherever possible.
Post prominent warning signs near the laser operating area (Figure 2-1).
Install the laser so that the beam is either above or below eye level.
Set up shields to prevent any unnecessary specular reflections or beams from
escaping the laser operation area.
When the target is not present, set up a beam dump to capture the laser beam and
prevent accidental exposure (
Do not block off access to any disconnect device such as the keyswitch, shutter

Emission and Status Indicators
The system provides the following emission and power indicators:
A white EMISSION indicator on top of the laser head (Figure 2-3) turns on about 3
seconds before actual emission occurs.
The STATUS fault indicator (Figure 2-4) flashes amber during the harmonic crystal
warm-up sequence. When the unit is warmed up and all of the safety requirements
are met, the indicator turns green and blinks. This indicator turns red and blinks
when a fault has occurred.
Pin 14 of the ANALOG connector can be used to control an external emission
indicator.

External Safety Interlock
Interlock pins 8 and 13 (Figure 2-4) of the ANALOG connector must be connected for
normal system operation. They can be used in an interlock circuit to terminate laser
emission when a normally closed safety switch wired to these pins is opened. Such a
switch can be attached to an access point, such as an entry panel, that might be opened
unexpectedly. See
requirements.
Power Disconnect
The utility unit is provided with a grounded appliance inlet. To help maintain the safety
of the equipment, it must be connected to a grounded connection. The ground should be
verified prior to use.
Access to the power connection cord should be maintained to allow the unit to be
disconnected from power in the event of an emergency.
ENABLE position allows the laser to be turned on when commanded.

Maximum Emission Levels
Maximum Emission Levels
Table 2-1 lists the maximum emission levels possible for the Millennia eV lasers. Use
this information for selecting appropriate laser safety eyewear and to implement
appropriate safety procedures. These values do not imply actual system power or
specifications.
The diode pump laser used in the Millennia eV laser system produces infrared light.
Laser light at longer wavelengths is generated in the production of green emission.
These wavelengths are confined to the inside of the laser head.

Operating the Laser via a User-Created GUI
The Millennia eV laser system can be controlled by a device provided by or software
written by the user. In this case, the following features must be provided for safety:
Keyswitch: Limits access to the laser and prevents it from being turned on. The
keyswitch can be a real key lock, a removable computer disk, a password that limits
access to computer control software, or a similar “key” implementation. The laser
must only operate when the key is present and in the ON position.
Emission indicator: Indicates laser energy is present or can be accessed. The
indicator can be a power-on lamp, a computer display that flashes a statement to this
effect, or an indicator on the control equipment specifically for this purpose. It need
not be marked as an emission indicator so long as its function is obvious. This
indicator is required on any control panel that affects laser output.
