66 -- ULTRAFAST TI-SAPHIRE LASER SYSTEM SOL 54362-JM-99 POC Jeanette Matthews phone 702-295-2700, fax 702-295-2088 E-MAIL: matthejl@nv.doe.gov, matthejl@nv.doe.gov. Salient Features for the pusled laser system: 1. Output Wavelength: 205 nm +/- 3 nm 2. Pulse length: 3 pico-seconds +/- 2 pico-seconds 3. Energy Per Pulse: 125 micro joules +/- 25 micro joules 4. Repetition Rate: 10 Hz 5. Spatial Mode: TEM00 6. Beam shape: Gaussian profile 7. Beam ellipticity: >75% round 8. Beam Divergence: < 1.5 mrad full angle 9. Beam Diameter: 5 mm +/- 3 mm, collimated 10. Polarization: >500:1 linear 11. Pulse to Pulse stability: <20% rms (1s) 12. Average Power drift (in 2 hour period, controlled temperature +/- 2 ): <5% 13. An alternate configuration allowing an optical "pickoff" of laser pulses after the mode-locked component of the laser system shall be provided. 14. The laser system will have the capability to be synchronized, with a timing jitter of <5 pico-seconds, to a stable, external timing source. Please respond by February 23, 1999.
