The research and progress of several important mid-infrared nonlinear optical crystals were reviewed in this paper. The crystal structure, nonlinear optical properties and the important applications of these crystals were introduced. We also present the difficulties encountered during the process of crystal growth. And the approaches to solve these difficulties were discussed. We believe that it is much valuable to obtain nonlinear optical crystals with good quality and suitable size. Finally, we discussed the future study of the infrared nonlinear optical crystals.
