介绍了高功率激光系统的谐波转换系统匹配角调节的离线-在线技术。研究了如何将CCD近场仪应用于离线调节三倍频最佳匹配角, 该方案与光能量判断和肉眼观察光强相比更可靠。实验结果表明三倍频最佳匹配角的调节精度达到20″, 能够满足工程应用的要求。

An online-offline program which is applied to find out the optimum matching angular of the frequency tripling of high power laser are intraduced in this paper. Comparing with determining the optimum matching angular by laser energy meter or naked eyes, the laser near field CCD diagnostic device is more reliable. The result shows that the adjusting precision of the optimum matching angular of the frequency tripling can reach 20″, which can meet the requirement of engineering application.
