according to the diode pumped light intensity distribution and property of YAG materials that varies with temperature

stimulated and analyzed the change process of temperature in laser crystal media with heat capacity mode using finite element method. In order to achieve this

a side-pumping geometry with a triangle uniform distribution was adopted and its thermal conduction model of laser crystal was established. Furthermore

the different thermal effect was discussed contrastively under condition of heat capacity

continuous pumping and pulsed pumping operations. Results show that this work is useful to the experiment of the heat capacity lasers.
