66 -- DIODE PUMPED SOLID STATE 532NM LASER SYSTEM SOL 52SBNB6C9214 DUE 081296 POC Keith Kennedy (301) 975-6325/Contracting Officer, Sandra L. Febach (301) 975-6326 The National Institute of Standards and Technology (NIST) intends to purchase one each DPSS 532-200 diode-pumped solid state 532nm laser system, part no. 0165-605-00, on a sole source basis in accordance with FAR 6.302-1 from Coherent Laser Group, Santa Clara, CA. NIST shall request a written quotation and anticipates an August 25, 1996, award. The laser shall fulfill all of the following requirements: single longitudinal mode (frequency) for large coherence length to allow high contrast interference fringes; operation at single frequency with a line width of less than (2 MHz and a coherence length )150 meters; single transverse TEM00 mode for sharp beam focusing and uniform beam profile; ring resonator design to eliminate spatial hole burning that causes multimode or multi-transition laser operation; 200mW of continuous wave ouput; wavelength of 532nm; power stability; optical noise equal to or less than 0.25% rms with a bandwidth of 10Hz to 10MHz; no mode hopping-the laser shall have an active feed back loop that automatically controls an intra-cavity tuning element to insure tracking of the fundamental laser mode; laser must be vertically polarized with a polarization ratio of )100:1; full output power within one minute of turn-on from a cold start; size less than 5 x 4 x 18 inches including the power supply; no cooling water or fan during recording - the laser shall operate without a fan for more than 10 hours of continuous operation on an optical table; short term noise shall be less than 0.25% rms over a bandwidth of 10 Hz to 10 MHz; warm-up time less than 5 minutes; warranty for full repair to full operation within 72 hours after written service request; useful life greater than 14,000 hours of operation; delivery FOB destination within 60 calendar days after contract award. See numbered Note 22. (0180)
