Abstract

The invention relates to the field of lasers, especially to an all-fiber 2 [mu]m wavelength laser. The laser includes a semiconductor-pumped solid state laser, a gain fiber, an output fiber grating and a laser transmission cable. An output fiber end of the semiconductor-pumped solid state laser is connected to one end of the gain fiber. The other end of the gain fiber is connected to one end of the output fiber grating. The other end of the output fiber grating is connected to the laser transmission cable. According to the invention, a continuous 2 [mu]m thulium laser is converted into a pulsed 2 [mu]m thulium laser by the gain fiber and is output by the fiber. The all-fiber 2 [mu]m wavelength laser has the advantages of low energy consumption and less attenuation.
