Laser system
Sources sought for:
1.) UV-2 11eV Laser system
General
-----------
- Only companies with proven instrument performance and experience operating 11eV lasers in the field will be considered
- Vendor must provide engineering assistance for positioning and interfacing the laser to the customer's ultrahigh vacuum chamber
Optical
-----------

Repetition rate: 200 kHz - 50 MHz (variable, with synchronization output trigger) Pulse duration: <100 psec Average power: > 5 uW over full repetition rate range Pulse bandwidth: < 1 meV, < 0.01 nm
Polarization: Linear
Focused spot size: 250um at sample position Output purity: <1uW of other wavelengths/harmonics emitted Beam height: 100mm
Mechanical/Electrical
-----------------
Laser dimensions: (1150-1200mm) x < 550mm x < 260mm Laser output flanges: NW40KF Electrical requirement: 110 - 125VAC 60Hz, single phase, 10A
Supplies: EIA-19-inch rack-mount compatible enclosures with 3m umbilical cable
Safety
-----------------
Safety Interlocks (Class IV laser system):
1. On/Off Key switch
2. Emergency Power-Off (EPO) switch
3. Integrated Laser Shutter
4. Two (2) short-to-operate user interlocks on separate circuits 5. Laser Cover Off interlock 6. Cable Disconnect interlock 7. Seed Light Sensor interlock
External Interface Functionality
1. Shutter OPEN/CLOSE
2. UV Power monitor
3. Fault state monitor
Gas supply
-----------------
Customer will supply Nitrogen gas for purging. Vendor must provide fitting for DESO Quick-connect. The customer will not be required to provide any other gas supply.
