The Department of Defense (DoD) is seeking proposals for the development of a Tunable Vacuum-Ultraviolet (VUV) Laser Source, aimed at addressing critical research needs in the VUV spectral region, specifically wavelengths from 50-215 nm. The objective is to create a fully tunable, MHz repetition-rate coherent laser source that can facilitate spectroscopic diagnostics of hypersonic flows and combustion studies, with specific requirements including continuous tunability, high photon flux, and sub-picosecond pulse duration. This innovative light source has significant potential applications in various fields, including biomedical research, materials science, and semiconductor manufacturing. Interested parties should note that the solicitation is set to open on May 28, 2025, with proposals due by June 25, 2025, and can find more information at the DoD SBIR/STTR website.
