重点介绍了声光开关与光脉冲单选器的基本工作原理, 设计了一种以声光开关为核心器件的小型化高速脉冲单选器, 该脉冲单选器具有消光比高、插入损耗低、性能稳定和结构小等特点, 可用于从锁模激光器输出光脉冲串中选取单个光脉冲作为前端系统的种子光源。

Basic working principles of acoustic-optic switch and single pulse selector were introduced, and a miniaturized high-speed single pulse selector with acoustic-optic switch as the core device was designed. The module owning the characteristics of high extinction rate, low insertion loss, stable performance and small structure, can be used to select a single pulse from the output pulse train of the mode-locked laser as the seed light source in the front-end system.
