Tunable Single Frequency UV Laser

Compact and rugged single-frequency pulsed UV lasers are needed for measurement of ozone and the hydroxyl radicals (OH). The determination of the concentration of OH in the atmosphere is central to the understanding of atmospheric photochemistry. The goal for this SBIR Phase program is to demonstrate and build a highly robust high-power fast-tuning single frequency pulsed UV laser near 308nm for OH IPDA lidar measurement by using high average power and high peak power singe frequency fiber lasers. The UV laser will exhibit a pulse energy of greater than 100uJ, pulse width of 5~10ns, and beam quality less than 1.3. We will build a deliverable prototype UV laser for NASA.

UV laser is needed for measurement of ozone and the hydroxyl radicals (OH). The determination of the concentration of OH in the atmosphere is central to the understanding of atmospheric photochemistry. This proposed tunable narrow linewidth laser near 308nm can be used for integrated path differential absorption (IPDA) lidar for OH measurement.

This tunable single frequency UV lasers can be used to build commercial lidar for gas monitoring applications, for optical sensing, and scientific research.

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
