| 摘 要： | 控制由机械装夹方式所引入的波前畸变以提高惯性约束聚变(ICF)输出光束的质量,是在大口径钕玻璃片主放大器结构设计中必须考虑的。提出了一种新的有限元变形结果与光学元件面形畸变之间的数据处理方式,并与传统方式进行了对比。基于新的数据处理接口,利用光机集成分析方法对大口径八边形钕玻璃片的支撑系统结构设计参数进行优化。优化的结果保证了由支撑系统引起的透过波前畸变小于十分之一波长,同时波前畸变与设计参数变动的相关性最小。

| Abstract: | Controlling the wavefront distortion introduced by mechanical mounting to raise the quality of output beam in inertial confinement fusion(ICF)facility must be considered in the structure design of the large aperture Nd :glass main amplifier.A novel method of data processing between the finite element deformation results and the surface distortion of optical element was presented and compared with the traditional method.The support system of large octagonal Nd:glass is optimized with integrated optomechanical analysis method based on the new data processing interface.The transmission wavefront distortion introduced by optimal support system is less than tenth wavelength and the correlation between the wavefront distortion and the design parameters variation is little. |
