Abstract

The influence of thermal effect induced by optical pumping on YAG crystal rod in a pulse solid laser on the wave surface of the output laser beam is studied in this paper. A series of time-resolved instantaneous interferograms during and after the pumping is obtained with a Mach—Zehnder interferometer, and three-dimension time-resolved pictures of the distorting wave surfaces and the curve of thermal focal length of laser rod versus time are gained after the treatment and calculation for interferograms.
