Fibertek reports on the design and performance of two high power ruggedized Thulium fiber laser systems designed for spaceborne and airborne applications. The spaceflight system is a 100 W average power, linearly polarized, 1940 nm thulium doped fiber laser (TDFL) packaged in a hermetic 11-liter module. The airborne system is an all-fiber, narrowlinewidth, master oscillator power amplifier architecture with staged thulium fiber amplifiers with 80 W peak power and 20 W average power in a quasi-continuous temporal waveform. The airborne laser includes programmable digital phase codes with bit rates up to several GHz. We will discuss the overall system performance and environmental qualification testing of both systems.
