When Your System Arrives
When the system arrives inspect the shipping containers for signs of rough handling or damage.
Indicate any such signs on the bill of lading. Report any damage immediately to the shipping
carrier and to a Spectra-Physics Customer Service Representative.
Retain the shipping containers. The containers will be required if the system is returned to the
factory for service. The containers may also be needed to support a shipping damage claim.
The packing list identifies all items that have been ordered. Check each item received against the
packing list, open all packages and inspect them for possible shipping damage. Make sure that
each system has a user’s Packet, which contains a USB stick. Note that some items may have been
installed at the factory. Report any missing or damaged items to Spectra-Physics.

Interface Requirements
The Quasar system can be controlled using the provided GUI, or signals applied to the LASER
CONTROL interface, or by a combination of serial commands and analog signals provided by a
host system.
You can use the following methods to control the Quasar system:
•Serial commands or GUI commands, which are convenient
•Analog signals through the BNC connectors
•Analog signals through the opto-isolated interface is fast, but requires circuitry for the
opto-isolated connections
•A combination of serial commands, and BNC inputs or analog signals
The combination of the flexibility of serial commands with the speed of BNC or analog signals
provide maximum control of the system. For manual operation, enter serial commands using the
Quasar GUI or a terminal emulator such as HyperTerminal.
USB connector Used in conjunction with the LASER CONTROL port to control the laser
system.
Alternatively, the SERIAL COM port (see below) can be used instead. Refer
to Appendix A, “Serial Command Interface,” in the User Manual for
instructions on how to control the laser using the serial command language.
Connect your control device (e.g., a computer) to this type-B connector using a
standard USB cable. The USB port is the recommended means of providing
serial control.

Baud Rate Default
The default baud rate is 19200. The GUI auto detects the rate, and will not run at any lower than 19200.
If you are having problems communicating with the laser, check the baud rate by turning the front panel
key switch. The system shows where the baud rate is currently set.
Inspecting and Unpacking
Before You Begin
Before unpacking, setting up, or operating the Quasar laser or any of its components, review the
safety information in Chapter 2, “Laser Safety and Compliance.”
Inspecting the Shipment
Your Quasar laser was packed with great care and its container was inspected prior to shipment—
it left Spectra-Physics in good condition. Upon receiving your system, immediately inspect the
outside of the shipping container. If there is any major damage (holes in the container, crushing,
etc.), insist that a representative of the carrier be present when you unpack the contents.
The three components of the Quasar system—the Quasar laser head, the Quasar power supply
(QPS), and the optional chiller—are shipped in separate crates.
The system is delivered in two crates (three if a chiller is ordered). Ensure you have enough space
in a clean environment to unpack the laser. Save all packaging material so if it becomes necessary
to return the laser it can be shipped in the proper containers.
System Components
Crate 1: Power supply and accessory kit; includes all cables, power cords, keys, interlocks, and
any optional items like hoses and fittings
Crate 2: Chiller (optional); includes Nalco, hoses, and AC power cords
Crate 3: Laser head
NOTE: The standard shipping configuration is with the exoskeleton installed. If lifting handles are
ordered they are mounted to the laser for shipment. If the optional shutter is ordered it is also
installed on the laser.
NOTE: If the optional chiller is not ordered, and hoses are ordered they will be packaged with the Quasar
Power Supply.

Tooling Requirements
An adjustable wrench to remove the (4) 5/16” bolts
A 5/32” hex ball driver (length ~ 10")
A hoist with load capacity of 181 kg (400 lb.) to move the laser from the crate onto the table
where it will operate

©Newport Corporation MKS Spectra-Physics Confidential 16 of 29
Lifting and Moving the Laser
Spectra-Physics has specifically designed two service handles (ordered separately) to assist in
moving the laser. Ensure that all the hardware is tight before moving the laser. Four people are
required to move the laser if the lifting handles are going to be used.
Use caution when lifting and moving laser. The laser head weighs 86 kg
(190 lb.). The QPS weighs 16 kg (35.27 lb.).
The table or transportation cart onto which the laser will be placed must
be capable of supporting at least 181 kg (400 lb.).
Best laser pointing is achieved if the mounting surface material is
aluminum.
Dropping the laser (even from a small height) damages the laser and
VOIDS your warranty.
The handles can be used to add safety straps to any lifting mechanism. The center of gravity is located
at the eye bolt. As the laser is lifted, maintain the center of gravity. Reposition the bolt as needed.

Unpacking the Laser System
For customers who integrate the laser into a tool, Spectra-Physics recommends that the laser be
shipped in its original container. The shipping crate offers the best protection. Spectra-Physics
further recommends that you repackage the laser and vacuum seal the laser in a new shipping bag.
You can find the laser head shipping kit in the FRU list.
Keep all shipping materials. If you file a damage claim, you might need them to demonstrate that
the damage occurred as a result of shipping. If you need to return the system for service at a later
date, the specially designed container ensures adequate protection.
Note that the Quasar laser head weighs 86 kg (190 lb.) and the QPS weighs 16kg (35.27 lb.). Four
people are required to move the laser head safely.
Unpacking the Power Supply/Accessory Kit Crate
Verify that the tilt and shock watches (see Figure 4-3) on each crate are not tripped, indicating
that the units were safely shipped. If they are tripped, carefully document any damage caused by
the carrier.
The shock watches are on the sides of each crate. If the indicator on either watch shows that the
crate has sustained possible damage, follow the instructions printed on the label, and notify the
carrier and your Spectra-Physics representative. If they are not tripped, proceed with the next
step.
Open the shipping crate and remove the power supply and accessory kit boxes.
a) Using metal cutters, cut the shipping band.
b) Unfasten the four clamps around the bottom of the crate that fasten the top portion of
the crate (the cover) to the palette. Turn the handles counter-clockwise and disengage
the latch as shown.
