摘要
终端光学组件是高功率激光驱动器的核心单元之一,承担着频率转换、光束聚焦、谐波分离和测量取样等功能。通过光学和结构设计可以实现终端光学组件的基本功能,满足高功率激光驱动器开展各项实验的基本要求,但是激光导致的终端元件损伤问题和强紫外光传输带来的若干非线性效应是制约终端光学组件总体性能的关键问题。综述了国内外高功率激光驱动器终端光学组件的研究历程,分析了终端光学组件面临的主要问题,并探讨了终端光学组件设计的主要思路。
Abstract
Final optics assembly (FOA) is one of the most important parts in high-power laser facilities. The FOA primary functions include frequency conversion, focusing, wavelength separation and diagnostic beam sampling, which can be realized through optimized FOA optical and structural design. Such a design can meet the basic requirements of high-power laser facilities for different experiments. However, laser-induced damage of final optics and several nonlinear effects resulting from high intensity ultraviolet (UV) laser pulses are major concern during FOA design, construction and operation. This paper reviews the development process of FOA in high power laser facilities, analyzes the core consideration, and discusses the main solution in FOA design.
