Laser Linewidth Characterization Suite

The National Institute of Standards and Technology (NIST), Acquisition Management Division, seeks quotation for a Laser Linewidth Characterization Suite comprising two mode-hop free, widely tunable laser sources, with quotations due June 30, 2026. The procurement is unrestricted and conducted as a Request for Quotation (RFQ) under FAR Part 12 for commercial items.

Place of performance is Boulder, Colorado (325 Broadway, Boulder, CO 80305). The NAICS code is 334516, Analytical Laboratory Instrument Manufacturing, with small business size standard of 1,000 employees.

Item 1 requires a 980 nm laser source with continuous tuning from 920–990 nm, fiber-coupled output to polarization-maintaining fiber with FC/APC connector, output power greater than 17 mW across the range and maximum power of 35 mW or greater, tuning speed of 10 nm/sec or larger, absolute wavelength accuracy less than 100 pm, optical linewidth less than 1 kHz instantaneous and less than 10 kHz integrated at 5 microseconds, dual-stage optical isolation greater than 60 dB, and all-digital control electronics capable of locking and stabilizing up to four external lasers using PDH-locking and Lock-In signal generation. Item 2 requires a 780 nm laser source with continuous tuning from 750–790 nm, output power greater than 14 mW across the range and maximum power greater than 20 mW, optical linewidth less than 0.5 kHz instantaneous and less than 10 kHz integrated at 5 microseconds, and comparable control electronics. Both systems must be electrically pumped diodes with mechanical motor step size of 0.3 pm or better, piezo-electric tuning ranges of 55 GHz and 60 GHz respectively, and minimum one-year manufacturer warranty or 3,000 operating hours. Delivery and installation must be completed no later than 30 weeks after receipt of order.

Evaluation uses a Lowest Price Technically Acceptable (LPTA) methodology, with technical capability evaluated as Acceptable/Unacceptable and price evaluated for reasonableness. Quotations must include firm fixed pricing with shipping to NIST, delivery timeline, country of origin/manufacture, SAM Unique Entity ID, and remain valid for 120 days. Payment terms are Net 30. Amendment 1 corrected contact information; all communications must reference solicitation number NB686100-26-01536 and be sent to angela.hitt@nist.gov.
