Ultrastable Optical Reference Cavity System

This solicitation, issued as a Request for Quotation under number NB688000-26-01743, seeks the procurement of a single 1396 nm ultrastable optical reference cavity system from the National Institute of Standards and Technology (NIST), part of the Department of Commerce, for use in a quantum sensing project focused on developing a strontium optical lattice clock with integrated photonics. The system must meet exacting technical specifications including a primary operating wavelength of 1396 nm with a finesse between 200,000 and 400,000, and a secondary wavelength of 689 nm with a finesse ranging from 1,000 to 20,000. Performance criteria require thermal noise fractional frequency stability of 6 × 10⁻¹⁶, enabling a stabilized laser linewidth of less than 1 Hz, along with a modified Allan deviation of 6 × 10⁻¹⁶ at one second averaging time at 1550 nm, near zero crossing of less than 15 kHz/day equivalent, and fractional acceleration sensitivity of less than 1 × 10⁻¹⁰ per g along all axes. The offeror must provide a turn-key installation with a vendor technician on site, deliver all necessary electronic media—including software, electronic manuals, and a license key—and ensure the system is shipped via FedEx or similar commercial carrier directly to the facility in Boulder, Colorado, following strict handling protocols for sensitive laser equipment. Delivery, installation, and training must be completed no later than 20 weeks after award. The system must include a manufacturer’s warranty covering labor, parts, travel, and liability for returns for a minimum of 12 months or 3,000 hours of operation, whichever comes first. Training must be provided in operations, maintenance, troubleshooting, and safety, coordinated through the Technical Point of Contact or Contracting Officer’s Representative. Access to the NIST facility in Boulder requires U.S. citizenship; foreign nationals must be pre-registered 30 days in advance. Government acceptance of the system is expected to require at least two months to account for the extended setup and stabilization times needed for performance characterization, even though planned testing is scheduled over seven business days. While the solicitation does not specify evaluation factors, payment terms, or detailed packaging requirements, proposers must demonstrate technical capability to meet all performance benchmarks and include a detailed installation
