SBIR/STTR
Highly Efficient 2 Micron Wavelength Fiber Laser, Phase I
Project Introduction
Thulium doped fiber laser near 2 micron is of great interest because of the prospect of combining high efficiency, high output power, and retina safety together. This proposal is for the development of highly efficient 1.94 micron fiber laser as the pumping source of Ho doped crystal lasers for LASA's lidar applications. New Tm-doped glasses and fibers will be developed, high efficient fiber lasers will be demonstrated, and a new laser configuration suitable for NASA's application will be designed and demonstrated.

Anticipated Benefits
Potential NASA Commercial Applications: Pulsed laser at 2.05 micron wavelength can be used in a Differential Absorption Lidar (DIAL) to make precise, high-resolution CO2 measurements to investigate sources, sinks, and fluxes of CO2, particularly across the mid to lower troposphere. NASA Needs 2.05μm laser transmitter with high efficiency and high output power. NASA needs 1.94 micron fiber laser as the pump source for the 2.05 micron laser transmitter because it offers several significant advantages including high electrical efficiency, low thermal load, compact size, low mass, long-lifetime, and rugged package.
