摘　　要：叙述了大口径高功率固体激光器，利用两块级联晶体的二阶非线性效应，对激光输出进行谐波转换，实现三次谐波输出的方法。介绍了实现倍频和混频过程所需的精密调整架的结构设计要点及其精度分析。研制的８套倍频器系统在同一台控制电源集中控制下，可获得高精度要求。The method for third harmonic generation of large aperture high power solid laser is described which is the second nonlinear effect of two cascade crystals in this paper.The key point of structure design and accuracy analysis in precision mount which is needed in the procession to obtain second and third harmonics generation is introduced.The perfected 8 sets of high precision frequency conversion scheme was controlled with a stepping motor driven poper supply and the high precision demand was satisfied.
