摘　　要：平面激光诱导荧光是基于片状激光光束,激发流场中自由基或示踪粒子辐射荧光,通过对该荧光成像获得流场空间分布信息的一种成像诊断技术。脉冲串激光器是目前能够满足高速平面激光诱导荧光技术对高重频、大能量激光光源需求的有效光源。本文针对应用于高速平面激光诱导荧光成像诊断中的脉冲串激光器进行了综述,对比了脉冲串激光不同产生方式的特点,阐述了发展状况,并对作为高速激光诊断光源的脉冲串激光器的发展前景做了展望。Planar Laser-induced Fluorescence (PLIF) is an imaging diagnostic technique that is based on the sheet laser beam, fluorescence emission from free radicals or tracer particles in a stimulated flow field, and the spatial distribution information of the flow field obtained through fluorescence imaging. Currently, the burst-mode laser is an effective light source that can satisfy the requirements of a high repetition rate and high energy laser source for high-speed PLIF technology. The study provides a comprehensive overview of burst-mode lasers used in high-speed PLIF imaging diagnosis. The characteristics and development of different burst-mode lasers are compared and explained. The prospects of burst-mode lasers as high-speed laser diagnostics light sources are also presented.
