1.26 Single Frequency Fiber Laser, Phase I

This proposal is for the development of an innovative compact, high power, and extremely reliable 1.26 micron Ho-doped single frequency fiber laser. The proposed single frequency fiber laser consists of Raman pump laser and single frequency 1.26-micron fiber laser, which will be constructed by using Ho3+-doped fluoride glass fiber. A Raman fiber laser is used as a resonant pump laser source for Ho3+-doped fiber laser. High gain per unit length can be achieved in Ho3+-doped fluoride glass fiber due to the strong resonant pump. This type of fiber based seed laser is needed for remote sensing of O and O -N for measuring atmospheric pressure. The single frequency 1.26-micron fiber laser with high-speed frequency modulation capability and electronic control, which will be developed in Phase II as part of the seed laser, can be used to build coherent laser radar to perform instant measurement.

There are several potential non-NASA commercial applications. The 1.26 micron seed laser can be used for commercial coherent LIDAR, remote sensing for environment monitor, and non-linear frequency conversion.

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.
