Single Frequency Lasers for Space-Based Wind and Aerosol Lidar, Phase II

Stable, single-frequency cw lasers operating at 2 µm and at 1064/532/355 nm are needed in a number of lidar systems that are being planned for NASA airborne and space-based lidar systems. These include the following.

Stable, single-frequency cw lasers operating at 2 µm and at 1064/532/355 nm are needed in a number of lidar systems that are being planned for NASA airborne and space-based lidar systems. These include the following. 1. Direct Detection Doppler Wind Lidar systems that operate at 355 nm. 2. Coherent Wind Lidar systems that operate at 2 µm. 3. High Spectral Resolution Lidar systems that operate at 1064/532/355/nm. 4. Ozone DIAL systems. At least two missions that have been recommended by the NRC Earth Science Decadal Survey will need the technology that we propose to develop. These are the 3D-Winds mission and the ACE (Aerosol/Clouds/Ecosystems) mission. We have identified the following three possible non-NASA commercial applications. 1) Fourier Transform Spectroscopy for remote sensing applications. A stable and robust single frequency 1064 nm source is needed to support these activities. 2) Direct Detection Wind Lidar development at a number of aerospace companies. We have identified at least four companies that are interested in using the technology we are proposing to develop as a part of wind lidar systems that they are developing for balloon-based, airborne, and space-based applications. 3) Development of an aircraft based water vapor lidar for atmospheric studies of the troposphere. A 1064 nm seed laser will be needed for the water vapor lidar we have jointly proposed to build.

This is early/mid-stage (TRL 4) — 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.
