Cr ~ (2 +): ZnSe has a wide absorption band and emission band, and is an excellent tunable laser material in the mid-infrared band. The laser output performance of Cr ~ (2 +): ZnSe crystal was studied from absorption spectrum, emission spectrum and angular tuning output. The Cr 2 +: ZnSe crystals were prepared by vacuum high temperature diffusion method, and the ZnSe crystals with a thickness of 1.7 mm and a diameter of 10 mm doped with Cr 2 + ions were obtained. Using a Tm ion-doped fiber laser with a center wavelength of 2.05μm and a maximum output power of 8 W, a cavity was constructed by using a flat cavity. The maximum average power of 1.034 W, the center wavelength of 2.367 μm and the line width of 10 nm were obtained. Laser output. The tuning performance of Cr: ZnSe crystal was studied by means of angle tuning, and the tuning output was obtained in the range of 100 nm.
