| 摘 要： | 通过对高能量密度激光器运行过程中腔镜存在的表面及背面吸收热量的有限元分析，得出腔镜表面在不同吸收热流密度和约束条件条件下热变形分布。指出提高腔镜反射率，改变腔镜的基底材料以及优化腔镜的约束条件是显著降低腔镜反射面变形的有效途径。

| Abstract: | Through the Finite Element Analysis (FEA) on the resonator mirror, which absorbs the heat at the front and back surfaces during the operation of high-energy density laser, the thermal displacement distributions are presented under different heat flux and constraint conditions. It is indicated that improving the reflective rate, adopting new mirror substrate material and optimizing the constraint condition of the mirror is an effective method for reducing mirror thermal deformation. |
