Description

technical field [0001] The invention relates to the technical field of lasers, in particular to an optical fiber gas laser generating device for generating 1.5 μm laser. Background technique [0002] The 1.5μm band laser has important application value in the fields of optical fiber communication, biomedicine, environmental monitoring and industrial processing, and has always been a hot spot of international research. Tunable, narrow linewidth, and high peak power 1.5μm band lasers can be used as ideal light sources for supercontinuum lasers, infrared gas lasers, or optical parametric oscillations. At present, the 1.5 μm light source is mainly obtained by rare earth ion-doped solid glass fiber lasers, but due to the low damage threshold of solid doped fibers and strong nonlinear effects, it is difficult to further increase the output laser power. Although the 1.5μm band laser with high peak power can be output by mode locking, Q switching and other methods, the nonlinear ef...
