摘要
阐述了对国际上正在发展的高能激光系统核心特征量的理解。分析了影响这个核心特征量的若干要素:主激光器选择变化的历史轨迹及其原因;光束质量是高能激光系统的生命线,做好光束质量是一个多环节的科学工程;分析了这一技术链条上游、中游和下游的技术难点以及与其都有关系的全系统的稳定性问题。最后,把这些要素结合起来,可将核心特征量综合表达为目标上的激光亮度。
This paper elucidates our understanding of the key characteristic quantity of high energy laser（HEL） system which is rapidly advancing in the world.Factors influencing the key characteristic quantity are analysed： the evolution history of principal laser and its reasons;as beam quality is the lifeline of HEL system,and to gain a better beam quality is a multilink-chain scientific engineering,technical challenges in the upper,middle and lower reaches along the technical chain,as well as the stability of the whole HEL system are discussed.In the end,by combining all the factors of contribution,the key characteristic quantity is expressed as the laser beam brightness on the target.
