66 -- Q-SWITCHED ND:YAG LASER SOL NRMGB000900206 DUE 070799 POC Michelle Bernal, Purchasing Agent, (303) 497-3983 or FAX (303) 497-3163 E-MAIL: NOAA; MASC Acquisition Management, Michelle.A.Bernal@noaa.gov. The National Oceanic & Atmospheric Administration (NOAA) has a requirement for a Q-switched ND:YAG laser with second, third, and fourth harmonics. The atmospheric chemical kinetics program area of the NOAA=92s Aeronomy Laboratory is involved = in studies of photochemical processes, reactions of free radicals, and heterogeneous/multi phase reactions that are important to the Earth=92s atmosphere. Current areas of research include stratospheric ozone depletion, tropospheric chemistry, and photochemical experiments where tunable, high energy, UV pulses are needed for photolysis. Specifications are as follows: 1)The purchased laser will be used to pump a dye laser (Spectra-Physics/Quanta Ray PDL) that we already have. Therefore, it is imperative that the purchased laser be compatible with the dye laser. 2)The laser will be used in conjunction with other 10 Hz lasers. Therefore, the purchased laser must be capable of (a) running at 10 Hz and (b) being externally controlled via TTL or similar pulses. Pulses needed for external control will be provided by the user. 3)Because of the required high energies, the following MINIMUM energies PER PULSE at the specified wavelengths at 10 Hz must be available: (a) greater than or equal to 850 mJ at 1064 nm (b) greater than or equal to 450 mJ at 532 nm (c) greater than or equal to 220 mJ at 355 nm (d) greater than = or equal to 90 mJ at 266 nm. All these wavelengths should be produced without having to add or take away another module of crystal(s). 4)Space is a premium in the laboratory and the laser has to fit in the existing space. The purchased laser will be underneath an existing dye laser and the beam will be directed up to the dye laser. Therefore, dimensions of the laser are extremely important. (a) the laser head has to be separate from the power supply (b) the dimensions of the laser head has to be as follows: (i) less than 50 inches long (along the axis of the laser output). (ii) less than 15 inches wide. (iii) less than 15 inches high. 5)In addition to pumping the dye laser, the purchased laser will be used in other roles. The laser will be frequently used = as a source of 1064 nm or in such a way that the third (355 nm) and the second (532 nm) harmonics will be used together. So, the 355 and 532 nm beams from the same pulse should be available separately, when needed. When used to get the both 355 and 532 nm pulses, it is understood that the energy at 532 nm will be substantially lower. The laser must also provide the full energy at 1064 without having to take out the harmonic generation module. In this mode, it is = understood that none of the harmonics will be available. 6)The laser must be capable of producing user selectable output pulse widths of 8 ns and 2.5 ns. The short pulse width, when employed will provide larger peak powers that are needed in some experiments. 7)The harmonic generators should be rotatable to provide user-selectable polarization. 8)The harmonic generator should be sealed and desiccated to provide protection. Stability is also a factor. So, water-cooling would be desirable. 9)The laser should be protected from dust and other chemicals to keep the optics clean in a chemical laboratory. 10)Changing flash lamps must not require taking the laser head out of the laser to avoid laser cavity realignment. 11)Other standard specifications include: (a) full angle of beam divergence shall be less than 0.5 mrad (FWHM). (b) beam pointing stability less than plus or minus 50 microrad over a workday of 8 hours with constant temperature (plus or minus 2 C) (c) beam diameter should be less than 10 mm. (d) pulse-to-pulse energy stability should be better than plus or minus 3 percent at 1064 nm for 99 percent of pulses over one hour. (e) power drift must be less than 4 percent at 1064 nm over a workday of 8 hours with constant temperature (plus or minus 2 C) (f) the flash lamps used to pump the rods must = last more than 25 million pulses (i.e., 4 months of operation for 40 hours per week). 12)The system should come with a good warranty (2 years) to cover all the electrical and mechanical components. It is understood that the optical components are more susceptible to damage and are not expected to be covered for 2 years. 13)It is imperative that the provider is a well-established company with a history of good service. References may be required from users who have employed the laser that is bid in research laboratory applications. Since service is often required on short notice, the company or its service engineer should be close enough to Boulder for quick service. An established track record is essential. The seller must provide warranty service during the warranty period by person(s) certified by the manufacturer. 14)The laser must be new and come with a set of complete manuals. 15)The laser should be installed in our laboratory = in Boulder without any additional cost. This procurement is being conducted per FAR Part 13, Simplified Acquisition Procedures. Procurements under Simplified Acquisition Procedures ($100,00 or less) are set- aside for small business unless small business cannot meet the need at = a reasonable price. There is no formal solicitation. All specifications are addressed in this synopsis. Technical merit as well as price will be used to evaluate offers. As technical merit becomes more equal, price becomes a greater factor. When submitting a quote, please include business size, Federal Tax ID number, and Duns and Bradstreet number. Terms and Conditions and = agency level protest procedures can be found on web site http: www.doc.gov/oam/conops/#REFERENCE. Hard copy in full text available from office address and phone number listed in notice. Anticipated award date will be July 9, 1999. Posted 06/15/99 (D-SN342977). (0166)
