摘　　要：该文介绍了应用于超快光纤激光系统中起选单、降频作用的光纤声光调制器的设计思路及应用试验,描述了声光调制器的工作原理。在46.6 MHz重频的超快激光脉冲下实现了同步、分频、模拟调制等功能,满足用户使用要求,并研制出光脉冲上升时间10ns,插损小于3dB的声光选单器产品。In this paper, the design idea and application experiment of fiber optical acousto-optic modulator for pulse picking up and frequency reduction in the ultra-fast fiber laser systems are introduced. The working principle of acousto-optic modulators is described. The function of synchronization, frequency de-multiplication and analog modulation under 46.6 MHz multi femtosecond laser pulse have been realized, which can meet the user requirements. A kind of acousto-optic pulse picker with the optical pulse rise time of 10 ns and insertion loss of less than 3 dB has been developed.
