초록
Thermo-mechanical responses of an Nd:YAG gain medium were analyzed under different cooling and constraint conditions using finite element analysis(FEA). In the gain medium, higher convection coefficients and fixed-temperature cooling conditions effectively reduced temperature rise and stress of the Nd:YAG gain medium, whereas insufficient cooling led to increased deformation. Four-point support of the gain medium improved structural stability compared to three-point support. These results provide useful guidelines for the opto-mechanical design of high-power solid-state lasers.
