长时热变形下硅反射镜的参量选择
Parameters design of silicon reflectors in long-time thermal distortion
摘要
Abstract
The paper investigates the output characteristics of a chemical oxygen iodine laser(COIL) affected by nonideal resonator mirrors. Various parameters in long-time thermal deformation of silicon mirrors, such as absorption factor, supporting radius, and thermal load, are considered. The simulation results show that the absorption of mirrors plays a key role in beam quality control. If the decrease in laser output power is required to be less than 20％ within the working time of 10 s, the absorption factor must be no more than 3.0 × 10-4. Furthermore, the beam size affects the supporting radius of four-point supporting. The additional phase aberration induced by mirror supporting deformation can be avoided as the supporting radius is greater than 1.4 times of the beam radius.关键词
