本文讨论了一种基于特征参量ΔS的用于二次谐波产生的非线性光学晶体的厚度优化的简单方法，该方法考虑了群速度失配和群速度色散。得到了厚度与最大二次谐波强度关系的近似解析式，可用于二次谐波优化。
A simple method of thickness optimization of a nonlinear optical crystal used for second-harmonic generation involving group-velocity mismatching and group-velocity dispersion is discussed on the basis of the feature parameter ΔS. An approximate analysis formula for thickness with respect to the maximum second-harmonic intensity is obtained, which is applicable to the optimization of second-harmonic generation.
