声光诱导单向运转的Nd∶Glass环形腔激光器

Acousto-Optic Induced Unidirectional Operation Nd∶Glass Ring Laser

在LDA侧面系浦的NdGlass环形腔激光器中，利用声光调制器控制激光单向运转，消除空间烧孔效应，获得单纵模输出，通过预激光调Q获得脉宽50ns、能量为1．4mJ的单纵模输出，理论分析的结果在实验上得到极好地验证。

A traveling wave acousto-optic modulator has been used to induce unidirec-tional operation in a LDA side pumped Nd.Glass ring laser. The laser can proudce singlefrequency output owing to elimination of the spatial hole burning effect- Via prelasingQ-switching, pulses hare been obtained with peak power of 28 kW(1.4 mJ, 5Ons) at 1.O53pm.
