Gain-switched all-fiber 3.5 μm laser with high pulse energy

We report the demonstration of an all-fiber pulsed laser at 3.5 μm based on gain-switching scheme. The cavity, formed by splicing two fiber Bragg gratings to a piece of Er-doped fluoride fiber, is dual-wavelength pumped by a pulsed 2 μm fiber laser and a continuous-wave 0.98 μm l...
