光阴极电子源是先进加速器装置最为关键的部件,驱动激光的品质参数是电子源性能的首要决定因素.近年来,电子加速器装置的束流指标不断提升,要求驱动激光具备高功率、高稳定性等特点和时空分布调控的功能,这对驱动激光系统的放大、选频、倍频、时空整形等模块提出了更高的需求.国内外主要研究机构根据其电子源的需求采用了相应的技术路线,在重复频率、激光波长、单脉冲能量和时空分布整形等方面各有特点.本文介绍了高亮度电子源驱动激光的主要技术路线和国内外发展现状,分析了典型的驱动激光方案,并讨论了驱动激光系统的未来发展趋势,以期为相关装置的规划和建设提供参考.
Photocathode electron sources play a crucial role in advanced accelerator facilities.Recent advancements in electron accelerator facilities have continually pushed the parameter boundaries of electron sources,which in turn necessitate photocathode drive lasers that possess high power,high stability,and the ability to control spatiotemporal distributions.For such a purpose,lots of efforts have been made to achieve high-quality amplification,harmonic generation,and spatiotemporal shaping of the drive laser systems.This paper presents a comprehensive review of the primary technological approaches and status of drive lasers for high-brightness electron sources worldwide.Analysis of representative drive laser schemes and discussion on the future trends are also included,aiming to provide a helpful reference for planning and developing high-performance photocathode drive laser system.
