The influence factors of the thermal effect of laser crystal were analyzed.Using the heat conduc-tive equation, the relationship between area of surface and thermal change of end face caused by the asymmetry distribution of inner temperature was deduced.The thermal distortion and thermal focus of common columni-form crystal and grooved crystal were calculated, respectively.And the results indicate that the thermal effect of laser crystal can be effectually improved by using the grooved crystal.
