NIST NB688000-26-00556 UV Frequency Doubler

The National Institute of Standards and Technology (NIST), Physics Measurement Laboratory, is soliciting quotations for one UV optical frequency doubler system under solicitation number NB688000-26-00556. The system must convert 534.0 nm input wavelength to 267.0 nm output wavelength with specific performance requirements including minimum output power of 15 mW at 200 mW input, input linewidth less than 100 kHz, and cavity lock bandwidth greater than 20 kHz. Key requirements include fiber-coupled input using PM460 optical fiber, Pound-Drever-Hall error signal generation, 19-inch rack-mounted digital control electronics with automatic relock capability, temperature-controlled non-linear optical crystal, and hermetically sealed cavity design with six-month stability without realignment. The procurement will be evaluated using Lowest Price Technically Acceptable (LPTA) criteria, with technical capability assessed on an Acceptable/Unacceptable basis and price evaluated for reasonableness. Quotations must be submitted electronically to matthew.delgado@nist.gov by March 25, 2026, with quotations remaining valid for 90 days from the due date.

This is an unrestricted procurement with no set-aside designation, available to all businesses meeting the technical requirements. The applicable NAICS code is 334516 (Analytical Laboratory Instrument Manufacturing) with a small business size standard of 1,000 employees. Delivery must be completed within twenty weeks after receipt of order (ARO) to NIST's facility at 325 Broadway, Boulder, Colorado 80305, with government acceptance expected within fourteen business days of receipt. The solicitation requires firm fixed-price quotations that include technical documentation demonstrating compliance with all specified requirements, a statement accepting solicitation terms or listing exceptions with rationale, the company's SAM Unique Entity ID, completed representations and certifications, and identification of any tariffs or customs charges if manufactured outside the United States. Vendor-provided on-site installation, equipment setup, and user training in alignment, optimization, and operation are mandatory requirements, with NIST supplying the 534 nm input laser as government-furnished material.
