abstract = "A 2 μm single-frequency, all-solid-state laser is one of the preferred light sources for coherent laser wind lidar and differential absorption lidar. In order to obtain 2 μm single frequency pulse laser with the high energy and hundred nanoseconds pulse width, the Ho:YAG non-planar ring cavity laser pumped by Tm:YLF solid state laser was used as the seed source to design and develop an injection-seeding single frequency Q-switched Ho:YAG pulse laser. A 2090 nm single-frequency pulse laser with an average pulse energy of 18.51 mJ and pulse width of 110.9 ns was obtained at a repetition rate of 200 Hz. The beam quality M2 factors of the output laser are 1.16 in the X direction and 1.25 in the Y direction, and the pulse spectrum width is 4.03 MHz.",
