| Abstract: | This paper explains the transient temperature distribution model and thermal stress distribution model of heat capacity slab laser in repetition rate operation, calculates nmnericaUy the models and compares with the conventional cooling scheme. Numerical analysis results show that the gain medium＇s temperature in interior is even lower than that on the surface, and the temperature grade is less; the calculation manifests that the interior of gain medium is tensile stress and its surface is compressive. |
