There are many crystal growth methods for nonlinear optical crystals, and each method has its unique advantages and applicable crystals. By understanding the characteristics of typical nonlinear optical crystal growth methods, the suitable method for the obtainment of a specific high-quality crystal could be determined. In this work, crystal growth methods for typical nonlinear optical materials are reviewed, such as hydrothermal growth of KTP crystals, aqueous solution growth of KDP crystals, organic solution growth of DAST crystals, high-temperature solution growth of BBO, LBO, KBBF crystals, bubble generation method for CBO crystals, Czochralski growth of LiNbO3 crystals , Bridgman growth of CdSiP2, ZnGeP2, BaGa4Se7 crystals. Ratio of the raw materials, solution preparation, temperature, pressure and other experimental conditions in these methods were described in detail. In addition, the pictures of the as-obtained crystal samples were displayed. Summary of the different crystal growth methods will facilitate the successful obtainment of the target crystal.
