Laser Linewidth Characterization Suite

The National Institute of Standards and Technology (NIST), through its Acquisition Management Division Team E-Boulder, is seeking quotations for a Laser Linewidth Characterization Suite under solicitation number NB686100-26-01536, issued as a Request for Quotation (RFQ) with a deadline of June 30, 2026. The requirement is for two manufacturer-new, mode-hop-free, widely tunable laser systems: one operating at 980 nm with a tuning range of 920 to 990 nm, output power exceeding 17 mW (maximum ≥35 mW), and an instantaneous linewidth of less than 1 kHz; the other at 780 nm with a tuning range of 750 to 790 nm, output power exceeding 14 mW (maximum >20 mW), and an instantaneous linewidth of less than 0.5 kHz. Both systems must include separate emission heads and control units, fiber-coupled to polarization maintaining fibers with internal optical isolators providing greater than 45 dB isolation. The control electronics must support all-digital stabilization of up to four external lasers with dual PID circuits per channel and phase detection and homodyne locking capability. Delivery, installation, and training are due no later than 30 weeks after award, with performance to occur in Boulder, Colorado. The system must meet all technical specifications upon delivery, with government acceptance expected within 14 days and a two-week evaluation period anticipated due to limited lab access. A minimum one-year or 3,000 operating hour manufacturer warranty is required. All submissions must be sent via email to angela.hitt@nist.gov and must include the solicitation number NB686100-26-01536. This procurement is set aside for all small business categories, classified under NAICS code 334516, and no government-furnished property is provided. The contracting office is located in Gaithersburg, Maryland, with Angela Hitt serving as the primary point of contact. No specific packaging, marking, invoicing, payment, or delivery terms are detailed beyond standard shipping, and no evaluation factors, inspection locations, or required certifications are provided in the documentation. Amendment 1 corrects contact information but does not alter any technical, delivery, or award conditions. No travel, site visit, security clearance, or bonding requirements are specified.
