58 -- UPGRADE FEMTOSECOND MODE-LOCKED LASER SYSTEM SOL NB815040804110JW DUE 071398 POC Jacqueline Wright (303) 497-5282, FAX (303) 497-3163 E-MAIL: NOAA; MASC Acquisitions Management, Brenda.S.Summers@noaa.gov. The National Institute of Standards and Technology (NIST) has a requirement for providing an upgrade to an existing ultrastable, low-noise, wavelength-tunable femtosecond modelocked laser system. The existing system is used as a laser source in several metrology tools. The requirement is for an increase in optical output power of both the pump laser and femtosecond laser and also an extension in the wavelength tunability range while maintaining all the pulse duration, pulse stability, power stability and noise, beam properties, pulse repetition frequency, and facilities requirements. The optical output power of the existing pump laser must be upgraded to be increased from the present more than 5W to over 10W power with 532 nm wavelength, +/-1% power stability over two hours, less than 0.1% rms noise over 10Hz to 2 MHZ. The beam must be 2 mm diameter TEMoo spatial mode with M-squared less than 1.1 and ellipticity less than 10%, with beam divergence less than 0.5 mrad full angle, and beam pointing stability less than 5 micron/degree C. The polarization must be greater than 100:1 vertical. It must operate on 110V drawing less than 20A with no cooling requirements other than our existing chiller, which must also cool the entire system, including the femtosecond laser. The laser head must have identical footprint, beam height, and remote controllability. The existing femtosecond laser must be upgraded to allow increased output power and extended tuning across the full 680-1090 nm range in the upgraded system configuration by installing and testing new optics sets for the 970-1080 nm range, and also modifying, installing and testing our existing optics sets for the 680-790 nm, 720-850 nm, and 840-1000 nm ranges. The pulse repetition rate is 82 MHZ, the noise must be less than 0.5% rms in a 10 Hz to 2 MHZ bandwidth, the power stability must be less than 5% over a two hour period, the beam must be TEMoo and less than 2 mm diameter, the beam divergence less than 0.6 mrad, and the polarization greater than 500:1 vertical. The existing laser presently operates with nearly bandwidth limited pulses with duration less than 60 fsec between 710-850 nm and sub 70 fsec between 850-980 nm using the three existing optics sets. Requirements are comparable typical durations across the entire tuning range provided with the new optics set and modified existing sets with specifications meeting sub 80 fsec pulses between 720-1000 nm, sub 130 fsec between 690-720 nm, and sub 130 fsec between 970-1080 nm with typical durations of 80 fsec to less than 100 fsec across 950-1090 nm. Required are typical output powers under the above pulse conditions approaching 1.6W at 810 nm, 300 mW at 690 nm, 800 mW at 920 nm, and 200 mW at 1080 nm, with specified powers of greater than 400 mW at 710 nm, 1.1 W at 790 nm, 600 mW at 900 nm, and 250 mW at 1053 nm, yet approaching the typical power outputs. The existing laser system was manufactured by Spectra- Physics. Spectra Physics is the only known manufacturer that meets these performance specifications and, as the manufacturer of the existing system, is also the only responsible source for modifying, testing, demonstrating full compliance with the performance specifications, and guaranteeing performance of the upgraded system and components including the existing femtosecond laser source, to achieve these performance specifications. The system shall also be completely warranted for one year. Interested sources must submit a written qualification statement and must contain sufficient information to clearly establish the ability to provide the necessary equipment upgrade by July 13, 1998. Responses must reference Synopsis No. NB815040804110JW. This announcement/solicitation is being issued under the Simplified Acquisition Procedures, FAR Part 13 (NTE $100,000.00) and is not a request for quotes as there is no bid package available. The award decision will be based upon the best value to the Government, with technical merit, past performance and availability being significantly more important than price. Termsand Conditions and agency level protest procedures are referenced at http://netsite.esa.doc.gov.oam. Technical questions can be directed to David Christensen at (303) 497-3354. In the absence of other qualified sources, it is the intent of the Government to negotiate on a sole source basis with Spectra Physics Lasers, Mountain View, CA. JACQUELINE WRIGHT, Purchasing Agent.
