66 -- HIGH STABILITY PUMP LASER SOL NHLBI-HL-P-95-110 POC Kathleen J. Van Steelant, Contract Specialist, (301) 435-0366. It is the intent of the National Heart, Lung, and Blood Institute (NHLBI) to acquire a High Stability Pump Laser for the fluorescence unit within the Laboratory of Cell Biology, NHLBI. The instrument must meet the following minimum specifications: MODE-LOCKED CONFIGURATION - 1) Repetition Rate: 80 MHz; 2) Power: ) 2 watts at 532 nm wavelength; 3) Pulsewidth: under 10 picoseconds; 4) Beam: TEM00 mode; 5) Stability: ( 1.75% peak to peak at 532 nm with ( 1.25% variation in a 2 hour period with +/-3 degree celsius environment; and 6) Power: 115v 60Hz 10A, no external cooling water. The high-stability pump laser system will be used to synchronously pump existing Spectra Physics 375 dye laser or Spectra Physics dye laser/cavity dumper combinations using either DCM or R6G dye. The hig-stability pump laser system shall produce ) 200 mW @ 600 nm @ 4 MHz with ( 6 picoseconds pulsewidth by employing ~1/2 of green beam (1 watt of 2 total). Proposals will be evaluated on the offeror's demonstrated understanding of the scope of work as shown by the ability to meet the required specifications, the offeror's experience with supporting and maintaining the existing dye lasers in the Laboratory of Cell Biology, the offeror's experience in providing and maintaining synchronously pumped lasers (including sales of complete systems and pump sources) and the offeror's proposed delivery schedule. A firm fixed-price type contract will be negotiated for this equipment. Delivery of the high-stability pump laser is anticipated within nine (9) months after contract award. Tests will be performed to ascertain that the equipment is functional before final acceptance. It is anticipated that Request for Proposal (RFP) Number NHLBI-HL-P-95-110 will be issued on or about August 14, 1995. Copies of the RFP may be obtained by writing to the National Heart, Lung, and Blood Institute, Contracts Operations Branch, Procurement Section, Rockledge Building 2, Room 6143, 6701 Rockledge Drive, MSC 7902, Bethesda, Maryland 20892-7902.
