Comb Stabilization Modules

The National Institute of Standards and Technology, Department of Commerce, seeks quotations for two Comb Offset Stabilization Modules (COSMO) for coherent operation of 1550 nm femtosecond frequency comb systems, with quotations due August 13, 2026 and questions due August 5. This is a total small business set-aside under NAICS 334515 with a 750-employee size standard.

Place of performance and acceptance is NIST-Boulder, Mail Stop 672.00, 325 Broadway, Boulder, Colorado 80305. The modules must accept PM1550 femtosecond laser input through FC/APC fiber coupling, supporting pulse energies between 200 pJ and 1 nJ with pulse durations of 180–250 fs. Key performance specifications include carrier-envelope offset signal-to-noise ratio greater than 35 dB measured in 300 kHz resolution bandwidth, integrated SMA RF output connectors, internal photodetector bandwidth of 100 MHz, and maximum average optical power of 400 mW. Vendors must possess an Export Control Classification Number and maintain an active Unique Entity Identification Number registered on SAM.gov at time of award.

Delivery shall be completed no later than 6 weeks after receipt of order, with acceptance not expected to exceed 7 business days. Base manufacturer warranty of 1 year is acceptable. Quotations must be firm-fixed-price with all shipping and delivery costs included, organized into three volumes: technical quotation, price quotation, and terms and conditions acceptance. Award will be made to the responsible quoter offering the lowest priced, technically acceptable quotation. Quoters must maintain active SAM.gov registration at quotation submission, during performance, and through final payment. Submit quotations electronically to Contracting Officer Lia Arthofer at lia.arthofer@nist.gov.
