    Abstract

    Applications requiring long-range atmospheric propagation are driving the development of high-power thulium fiber lasers. We report on the performance of two different laser configurations for high-power tunable thulium fiber lasers: one is a single oscillator utilizing a volume Bragg grating for wavelength stabilization; the other is a master oscillator power amplifier system with the oscillator stabilized and made tunable by a diffraction grating. Each configuration provides > 150 W of average power, > 50% slope efficiency, narrow output linewidth, and > 100 nm tunability in the wavelength range around 2 mu m.
