摘要
随着激光二极管技术的发展,以及一些先进热管理方案和新型加工工艺的涌现,固体激光器的输出功率已达到百千瓦量级,而光束质量的控制问题却日益凸显。本文归纳了板条激光器的光束质量控制技术,对当前已经实现了的几种技术路线进行了深入细致的分析,包括静态相位校正技术、非线性光学校正技术、自适应光学校正技术、几何光学校正技术等,并分别介绍了其工作原理、研究进展以及优缺点。
With the rapid development of laser diodes and the emergence of advanced thermal management technology and new processing techniques,the average power of solid-state lasers has already achieved levels of 100 kW in recent years,while problems with beam quality control become increasingly prominent.This paper summarizes the beam quality control technology of slab lasers.Several technical approaches are analyzed in detail,including the static phase corrector,nonlinear optics correction technology,adaptive optics correction technology,geometrical optics correction technology,etc.Their principle,current research progress,advantages and disadvantages are introduced respectively.
