| Abstract: | Based on the steady -state heat conduction equation, the temperature gradient and thermal in- duced stress of the doping concentration of 0.3 % Nd ： YV04 at crystal are numerical calculated, and thermal stress changing with the pumping power of a single crystal at the center and two end of pumping region are in- vestigated, meanwhile, pump power which the crystal can bear is calculated. It provides the basis for the development of the high power high beam quality slab laser. |
