NIST's Division 688, Neutral Atom Optical Clocks Group, requires a Magic Wavelength Laser for Ytterbium Optical Lattice Clocks to advance optical timekeeping. The agency is exploring an alternative wavelength at 460 nm, which offers potential clock advantages. The primary requirement is a high-power 460 nm ECDL (External Cavity Diode Laser) with specific technical specifications, including tunability between 457 and 461 nm, an instantaneous linewidth of less than 100 kHz, more than 10 GHz mode-hop-free tuning, and over 30 dB of optical isolation. The laser must deliver more than 400 mW after the isolator and include a digital controller with inputs for laser locking. The laser resonator should be machined from a single piece of metal for enhanced stability. The delivery of goods, installation, and any required training must be completed no later than 16 weeks ARO (After Receipt of Order). The warranty for the laser diode must be for one year or 3000 hours of operation, covering labor, parts, travel, and cost and liability for returns. Partial deliveries are acceptable.
The National Institute of Standards and Technology (NIST) is soliciting proposals for the procurement of a high-power 460 nm external cavity diode laser (ECDL) to support advancements in optical timekeeping through Ytterbium optical lattice clocks. This new magic wavelength offers potential improvements over the previously used 759 nm wavelength. The laser must have specific specifications including high power output (>400 mW), a narrow linewidth (<100 kHz), and a robust design for temperature and acoustic stability.
Additionally, the proposal outlines service needs such as delivery within 16 weeks after receipt of order (ARO), warranty provisions for one year or 3,000 hours of operation, and no specific training or installation requirements. It accommodates partial delivery and requires the vendor to ensure necessary shipping and operational conditions without the need for on-site visits.
The document emphasizes NIST’s commitment to enhancing optical clock technology and outlines detailed requirements to ensure the vendor can deliver a compliant product that meets the agency’s research objectives in high-precision timekeeping.
