二极管侧面泵浦声光诱导单向运转的Nd: YLF环形腔激光器

Unidirectional Operation of LDA Side Pumped Nd∶YLF Ring Laser Via Acousto Optic Effect

在半导体激光阵列侧面泵浦的ＮｄＹＬＦ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获得脉宽为５０ｎｓ，能量为１．２ｍＪ的单纵模输出。

A traveling wave acousto optic modulator has been used to induce unidirectional operation in a laser diode array (LDA) side pumped Nd∶YLF ring laser. The laser can provide single frequency output owing to the elimination of the hole burning effect. Via the prelase Q switching, pulses with peak power of 24 kW (1.2 mJ, 50 ns) at 1.053 μm are obtained.
