Fibertek has designed and is building a spaceflight (TRL 5-6) high-efficiency, high reliability (97.2% for 5-year mission) 100 W average, 1940 nm thulium doped fiber laser (TDFL) meeting all requirements for a NASA Earth Science spaceflight 2 μm Ho:YLF pump laser. These include polarization extinction ratio <16dB, diffraction limited beam quality, narrow linewidth (0.35nm) and >50% optical to optical efficiency. High reliability laser package, optimized for space environment and SWAP has size 10.6”x13.8”x4.4”and weight 30lbs. A summary of laser package design is presented, including structural and thermal analysis. Preliminary environmental testing results of the space laser are also presented. A spaceflight 100 W PM Tm laser provides a path to space for a pulsed, Q-switched 2 μm Ho:YLF laser with ~80 mJ/pulse at 100-200 Hz.
