The wedge-shaped lens is the key and special optical component of the final optics assembly (FOA) in high power laser facility. The wedge-shaped lens wedge angle measurement plays a remarkable role in focusing performance of high power laser. If processing angle and work attitude of the wedge-shaped lens deviate from the specific work angle, big surface deviation will be introduced into the FOA. Special shape of the wedge-shaped lens is not conducive to the measurements of the transmission profile and wedge angle. A set of wedge-shaped lens measurement adjustment programmes is proposed, including measurement of the wedge-shaped lens in processing process, and off-line measurement of wedge-shaped lens during alignment and on-line measurement during the debugging process. The scheme can ensure the processing precision and working attitude of the wedge-shaped lens, guarantee the beam quality and the positioning accuracy of the FOA components of high power laser system.

楔形透镜是高功率激光系统终端光学组件的关键元件，也是较为特殊的光学元件，楔形透镜的楔角测量关系着高功率激光的聚焦性能。终端组件中楔形透镜的加工角度、工作姿态一旦偏离了特定的工作角度，终端组件会引入大的面形偏差，楔形透镜特殊的形状不利于楔形透镜面形、楔角的测量。提出了一整套楔形透镜测量调整方案，包括楔形透镜加工过程中的测量方案，楔形透镜安装过程中的离线测量与调整方案，以及终端组件上线调试过程中的在线调试测量方案。该套方案的实施能够保证楔形透镜的加工精度，及组件中楔形透镜能够工作在最佳工作姿态，保障了高功率激光系统终端组件的光束质量和定位精度。

High accuracy of target aiming and positioning is required in the study of the inertial confinement fusion (ICF). A system based on the chamber center reference system, the target positing system and the target alignment sensor is designed. The finite element method is used for analyzing the static deformation and transient stability of this system, and it proposes a calibration method of the high resolution parallel light pipe to achieve the system coupling precision. It achieves target aiming and positioning precision better than 12 μm of the SG-II updated laser facility. Through the SG-II updated laser facility single laser beam across the Φ 800 μm hole target, the perforation efficiency is 97.5%. This provides a solid foundation for high accuracy targeting of the follow-up physical experiment′s requirement.
