689nm Laser

The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) is seeking a single 689 nm laser system tuned to the 689.44 nm atomic transition in strontium for precision spectroscopy and thermometry applications, under solicitation NB688000-26-01607. The laser must meet stringent performance specifications including an output power greater than 75 mW, a mode-hop-free tuning range exceeding 20 GHz, an instantaneous linewidth of less than 10 kHz, frequency stability under 100 MHz/K, and a tuning range of more than ±1.5 nm about the center wavelength. The system must include a dual-stage optical isolator providing at least 60 dB of isolation and more than 75% optical transmission. The contract is a requirements-type, firm-fixed-price agreement with delivery required FOB Destination to NIST’s Boulder, Colorado facility at 325 Broadway, 80305, within 26 weeks after receipt of order. The procurement is classified under NAICS code 334516 and is unrestricted, with no set-aside provisions. Quotations must be submitted electronically by June 2, 2026, to Lisa Stevens at lisa.stevens@nist.gov, on company letterhead, and must include separate price and technical volumes. The price quotation must be firm-fixed, include all shipping and delivery fees, remain valid for 90 days, and declare the country of origin. The technical submission must clearly demonstrate the proposed system meets all performance criteria with supporting documentation such as product literature and drawings. Award will be made on a Lowest Price Technically Acceptable (LPTA) basis, where technical capability is evaluated as pass/fail—offerors must demonstrate a clear and unambiguous understanding and ability to meet minimum requirements to be considered acceptable. Price will be assessed for reasonableness but not realism, and offers may be deemed unacceptable if option prices are significantly unbalanced. The contract incorporates numerous FAR clauses by reference, including those mandating compliance with Buy American requirements, prohibitions on contracting with inverted domestic corporations, cybersecurity safeguards (FAR 52.240-91, -92, -93), whistleblower protections, child labor prohibitions, and combating human trafficking. Offerors must maintain an active SAM registration with completed representations and certifications for NAICS 334516, including
