ffects of clamping methods for laser mirrors on thermal deformation
摘要
分析了当前大功率激光器腔镜采用的几种夹持方式特点,采用有限元软件计算了腔镜不同夹持方式下的镜面热变形和镜体最大应力,并对两种夹持方式下的应力破坏进行了分析.发现夹持方式对大功率激光器腔镜镜面变形影响很大,镜体边界沿径向固定的压圈法效果优于沿轴向固定的弹性压板法.
Abstract
It has been demonstrated that methods of clamping for laser mirrors affect thermal deformation greatly. The characteristics of several clamping methods are analyzed and the corresponding thermal deformation and largest stress of silicon mirror are calculated. It is concluded that the clamping method with buckling ring has an advantage over the pressing method with clamp plate in PV value of deformation on mirror surface. Moreover, the stress fractures for mirrors with these methods of clamping are analyzed.
