摘　　要：根据相位匹配条件和波矢曲面特性,更简单地导出光学倍频晶体非共线匹配产生二次谐波 的解析表达式,由此式易于求得与光轴共面、基波垂直光轴的非共线以及常用的共线等特殊情况下的相位匹配条件;并以实验验证了理论的正确性。According to phase matching conditions and the characteristics of wave vector curved surface, a simpler analytic expression for generating second harmonic by non-collinear matching of optical double-frequency crystal is derived. The phase matching conditions under the special cases, such as non-collinear on co-plane with optical axis, and fundamental wave vertical to optical axis and common collinear are easily obtained from the expression. The correctness of this theory is demonstrated with experiments.
