Laser System

The United States Naval Observatory is seeking a 448 nanometer laser system for use in a Sr lattice optical clock. The system must meet specific requirements, including a center wavelength at 448.176 nm, mode-hop free tuning range greater than 15 GHz, and an instantaneous linewidth less than 200 kHz. The system must also be turnkey, with current, temperature, and piezo control, and have electronic inputs for external feedback. The contractor must deliver the system to the United States Naval Observatory in Washington, D.C. by September 30, 2026. Key points to consider: • The laser system must meet the specified requirements, including wavelength, tuning range, and linewidth. • The system must be turnkey, with current, temperature, and piezo control. • The contractor must deliver the system to the United States Naval Observatory in Washington, D.C. by September 30, 2026. • The contractor must be registered in the System for Award Management (SAM) database to be considered for award.
