High-power passively Q-switched thulium fiber laser with distributed stimulated Brillouin scattering

We report a novel passively Q-switched 2 μm Tm3+ fiber laser simply by distributed stimulated Brillouin scattering with an all-fiber configuration. The maximum output power is 2.49 W with an optical-to-optical slope efficiency of 12%, and the laser wavelength is centered at ∼1991  nm with a spectral...
