摘要
用单透镜放大成像的方法进行了高功率激光焦斑实时测试。高功率远场焦斑经旋转椭球凹面反射镜取样后,通过单透镜放大成像系统将焦斑像消色差地放大成像到CCD图像采集系统上,通过数据处理得到可靠的焦斑形状和强度分布。该技术成功地解决了大型激光装置在极高功率下的基频和三倍频激光焦斑的实时测试问题,测试结果用其他测试方法得到了验证。
Abstract
Result of the focal spot measurement on the high power laser with single lens imaging method is reported in this paper. Focal spot of the high power laser is sampled by an ellipsoid concave mirror, and after passing through a single lens, it is imaged on the CCD system. With testing data to be processed, reliable focal spot shape and intensity distribution are obtained. In this way, real time test with the focal spot of the high power laser is realized. The testing result has been validated in other way.
