| Abstract: | :On the basis of the heat exchange equation ,the differences of the temperature and thermal stress of the laser medium between thermal compensation and uncompensation are analyzed. The analysis results are verified by using the finite element method and experiment. The experimental results agree with theoretical analysis |
