Summary

Description

NASA needs narrow linewidth lasers in the 1.5 or 2 micron wavelength regime for Lidar applications. The laser should be tunable by several nm and frequency modulated by 5GHz. Princeton Optronics has developed ultra-stable narrow linewidth diode pumped solid state lasers and developed high power Vertical Cavity Surface Emitting Laser (VCSEL) devices for fiber laser pumps as well as VCSEL pumped CW fiber lasers. In this SBIR, we propose to develop a fiber amplifier with a narrow line width seed laser for narrow wavelength output and the seed laser would be tunable and frequency modulated to a speed of 5GHz. By the end of the SBIR program we plan to deliver 10W level CW power fiber amplifiers with 10kHz linewidth in a small package. The package with the device would be space qualified and commercialized after development.
