Abstract

In this paper, we demonstrate the thermodynamic effects of the Nd:YAG Disk laser by pumping and cooling approaches, which is based on the theory of analytical thermal analysis. The thermal models are established to analyze the working characteristics of the Nd:YAG disk crystal, and they match the actual working state of the disk laser crystal. The analytical expressions for temperature field within Nd:YAG disk crystal are yielded by using a new approach to solve the heat conduction equation of isotropic material. The analytical expression of thermal distribution of the Nd:YAG disk crystal is obtained to analyze the thermal distortion field and additional optical path differences caused by heat in the Nd:YAG disk crystal. In the end of this paper, a series of the numerical simulations are performed to demonstrate the thermodynamic analysis of the Nd:YAG disk crystal in different methods of pumping and cooling. The numerical simulation results match well with the academic outcomes on the whole.
