摘　　要：以磷酸二氢钾(KDP)/磷酸二氘钾(DKDP)、三硼酸锂(LBO)、硼酸氧钙钇(YCOB)和硅酸镓镧族铌酸镓镧(LGN)为代表的非线性光学晶体已经在紫外到中红外的系列激光技术中获得了重要应用,长期受到国内外同行的广泛关注,其品质的提升和口径的扩大成为了当前国际竞争的焦点。着眼于强激光的重要需求,综述了KDP/DKDP、LBO、YCOB和LGN等重要非线性光学晶体的研究现状,介绍了其在大尺寸单晶生长及非线性光学性能等方面的研究进展,分析其在强激光非线性光学领域的应用前景。最后讨论了强激光用非线性光学晶体可能的发展方向和重点。Nonlinear optical crystals represented by potassium dihydrogen phosphate(KDP)/potassium dideuterium phosphate(DKDP),lithium triborate(LBO),yttrium oxycalcium borate(YCOB),and langanite(LGN)have obtained important applications in the series of laser technologies from ultraviolet to mid-infrared,and have been widely concerned by the researchers for a long time.The improvement of crystal quality and the expansion of aperture have become the focus of current international competition.In this paper,focusing on the important requirements of high power laser,we review the research status of important nonlinear optical crystals such as KDP/DKDP,LBO,YCOB,and LGN,introduce their research progress in the growth of large-scale single crystals and nonlinear optical properties,and analyze their application prospects in the field of nonlinear optics with high power laser.Finally,the possible key development directions and emphasis of nonlinear optical crystals for high power laser are discussed.
