Ultrastable Optical Reference Cavity System

The National Institute of Standards and Technology (NIST), under the Department of Commerce, is conducting market research via a Request for Quotation (RFQ) identified as solicitation number NB688000-26-01743 for an Ultrastable Optical Reference Cavity System operating at 1396 nm. The system is intended to support advanced quantum sensing and optical lattice clock applications, requiring highly precise thermal stability, vacuum housing with invar mounting, integrated ion pumps, heaters, thermistors, and vibration isolation components to meet stringent performance metrics including a fractional frequency stability of 6×10⁻¹⁶, laser linewidth narrower than 1 Hz, and acceleration sensitivity below 1×10⁻¹⁰/g. The complete delivery includes installation, on-site setup, detailed performance characterization, and user training to ensure operational readiness at the Boulder, Colorado facility. Although this document is a market research “Sources Sought” notice rather than a formal solicitation, the expected delivery and installation timeline mandates completion within 20 weeks after receipt of order, with government acceptance testing lasting up to two months due to the system’s complex stabilization requirements. This market research phase does not include finalized contract clauses, award criteria, or pricing information. No standard Federal Acquisition Regulation (FAR) contract clauses or evaluation factors are identified at this stage. Packaging and shipping must be conducted via commercial carriers such as FedEx, ensuring safe containerized transport. Special contract requirements include the presence of a U.S. citizen on-site during installation, mandatory preregistration of any foreign nationals 30 days in advance, and clear identification of the product’s country of manufacture to comply with potential Buy American Act and small business set-aside considerations. Responses are limited to four pages and should be submitted electronically to the Contracting Officer, Angela Hitt. The NAICS code for this procurement is 334516, corresponding to analytical laboratory instrument manufacturing, with indications that potential award strategy and contract type will be determined in subsequent phases.
