Introduction

Congratulations on your purchase of a Spectra-Physics system. This guide describes pre-

installation information for your laser system.

Some preliminary planning is essential to avoid unnecessary delays during installation and to

ensure easy operation and access to your system. You are requested to carefully consider your

operating environment prior to installation. Proper water/coolant, power and room

temperature are required for each system.

A checklist of pre-installation considerations is provided in this guide. You are responsible for

meeting these requirements prior to installation, with due consideration given to all applicable

building and safety codes.

We at Spectra-Physics intend to provide you with responsive support so that you can derive great

satisfaction and value in using our systems for your applications. We are available to you at 1-

800-456-2552.

Pre-Installation Checklist

Physical Location:

A location with adequate clearance around system to conduct service and accessible by Spectra-

Physics personnel.

A temperature controlled room.

Utility services have been installed.

Local building and safety codes are in compliance and have been verified.

When the system Arrives

Inspection

When the system arrives, any sign of damage to the shipping crates should be brought to the

attention of the delivering freight company. A claim must be filed with that commercial carrier

(usually within 30 days). Notify the originating Spectra-Physics office of any shipping damage.

Shipping damage is not covered by Spectra-Physics.

Your packing list will show all items that you have ordered. Open all the packages and check each

item for possible damage during shipping. Check the items against your packing list. Some items

may have been installed at the factory.

Each system comes with a manual; verify that you have received this item.

Please report any missing or damaged items to Spectra-Physics, or you may contact your Spectra-

Physics’ Sales Engineer.

Before the arrival of your Spectra-Physics’ Service Engineer please review the

following pre-installation requirements. When all the requirements have been met,

initial the boxes and fax a signed copy to the Spectra-Physics Service department at

(408) 980-6921.

Review Instruction Manuals

Please read the manual to get vital information about your system. Familiarize yourself with the

system. You are encouraged to spend as much time as possible reviewing the system

components before your Spectra-Physics’ Service Engineer arrives for the installation and

training.

Laser Safety Considerations

In addition to reviewing the sections in the manual regarding laser safety; be sure to have the

proper safety glasses available for ALL lab personnel present during the installation and testing

of your system. For more information, please call Spectra- Physics at 1-800-456-2552.

Diagnostics

During the course of installation, power measurements will be demonstrated on all of the

appropriate wavelengths. Your Service Engineer can identify which specifications will be

demonstrated and the equipment necessary to conduct such tests. A non- standard system will

require special consideration.

To have other published specifications demonstrated, consult with your Service Engineer to

determine whether additional diagnostic equipment will be required.

Before the arrival of your Spectra-Physics Service Engineer please review the following

pre- installation requirements. When all the requirements have been met, initial the

boxes and fax a signed copy to the Spectra-Physics Service department at

(408) 980-6921.

Pre-Installation Considerations

Location and Environment

The location of the system and environment of your lab should have the following features:

A safe location that meets all applicable building codes.

Easy access with adequate clearance around the instrument.

An optical table that will meet the space requirement of the instruments to be installed.

Proper air conditioning could be critical for the performance of the laser.

For certain applications ambient room temperature changes may be an important factor for the

laser system’s performance. Air ducts should not blow directly on laser or optical path.

To ensure stable day-to-day operation, the recommended minimum and maximum operating

room temperatures are 20 - 25°C. Room temperature should ideally be 22°C and should not

fluctuate ±1°C during any two-hour period.

See specifications in Table 1-1 and table 1-3 in the User’s Manual.

In some applications vibration isolation may be required for your system. Structural integrity of

the flooring could play an important role.

Please note that the laser head is very heavy and requires a sturdy and stable optical table.

Consider room requirements for future maintenance and upgrades by your Spectra-Physics Field

Service Engineer.

System Components

The Ascend laser system is comprised of four basic components:

1. Ascend laser head

2. Model APS-160 power supply

3. Ascend control software installed on a system computer

4. Refrigerated Chiller

RoutineMaintenance

The Ascend laser system was designed for minimal maintenance. Follow the routine procedures

described in this chapter to keep the system in good working condition for the life of the laser.

For further information, contact your Spectra-Physics service representative.

Pre-Installation Considerations (Continued)

Cleaning the Output Window

The Ascend cavity is sealed to keep the internal optics clean. The optical cavity should never be

opened. Depending on the cleanliness of the operating environment it is possible that dust or

debris can accumulate on the output window external surface, which might affect the output

power of the laser.

If the output window is contaminated, a spray of very clean, dry air or nitrogen can help remove

it. The pressure should not be more than 10 psi to avoid damaging the window.

Never try to clean the output window while the laser is operating. Such an action could result in

serious physical injury. Always make sure the laser is off and the AC power is disconnected before

attempting to clean the window.

The output window is antireflection coated to minimize power loss and back reflections. It can

be damaged by incorrect contact cleaning. The window can be cleaned with lens tissue

dampened with methanol, but it is difficult to accurately reach the optical surface. It is

recommended that you contact your Spectra-Physics service representative for additional

window cleaning techniques, if needed.

Do not remove the optical cavity cover or the window seal for any reason, or you will void your

warranty and may damage your laser.
