The U.S. Naval Observatory (USNO) is seeking to procure a frequency-comb system, referred to as the "Quattro Comb," to support its Precise Time Department's efforts in atomic clock technology using optical spectroscopy with calcium. The system must be centered around 1560 nm and deliver exceptional frequency stability to multiple wavelengths (1315 nm, 915 nm, 846 nm, and 862 nm) while stabilizing RF outputs of 10 MHz and 100 MHz. It should include robust features such as automatic mode-locking, external user-laser integration, and high signal-to-noise ratio balanced detection units. Emphasis is placed on achieving narrow linewidths and long-term stability for both the external lasers and frequency-comb outputs. The procurement timeline allows for component delivery within nine months of award. The no-travel policy underlines that all work will be coordinated with designated USNO points of contact at their Washington, D.C. facility. This request aligns with the USNO’s mission to maintain authoritative time standards for the Department of Defense, necessitating specialized, cutting-edge technology not readily available commercially.

The announcement from Naval Supply Center (NAVSUP) Fleet Logistics Center (FLC) Norfolk seeks to identify qualified suppliers for a Fiber Frequency-Comb System for the United States Naval Observatory. This document is a sources sought request, meaning that it is not a solicitation for proposals, nor does it imply a commitment from the Government or offer compensation for submitted information. The relevant North American Industry Classification System (NAICS) Code is 334516, with a size standard of 1,000 employees. Interested parties must respond by providing their company's details, including size classification and experience, along with a capability statement that outlines their ability and technical expertise to fulfill the requirements. They should also identify potential issues that may affect the project's success and suggest any changes to the Government's NAICS classification. Responses are due by February 10, 2025, by 5:00 PM EST and will be handled with confidentiality. This source sought aims to facilitate market research and planning for the upcoming contract.
