摘　　要：为了研究脉冲输出波长为1319nm的 Nd：YAG激光器,通过分析Nd： YAG激光介质的辐射跃迁能级, 采用镀制高选择性介质膜的方法抑制1064nm等其它波长的起振,最终实现1319nm激光单脉冲输出.实验中采用闪光灯抽运、水冷Nd： YAG激光器,KD＊P调Q,平平腔结构,获得1319nm激光静态输出能量340.9mJ,动态输出76.8mJ,重频1Hz,脉宽17ns,束散角2.7mrad.结果表明,通过镀制高选择性介质膜的方法可以实现1319nm激光调Q脉冲输出.In order to study pulsed electro-optic Q-switched Nd：YAG laser at 1319nm, the transition radiation energy level of Nd：YAG crystal was analyzed. A single pulsed laser at 1319nm was acquired after restraining laser oscillator of wavelength at 1064nm through coating chosen film on the mirror. In a configuration of lamp pumped, water-cooled Nd：YAG with KD＊P as electro-optic Q-switched, pulsed output static energy of 340.9mJ at 1319nm, Q-switched output energy of 768mj with pulsed- width of 17ns and divergence of 2. 7mrad were acquired. Experimental results show that coating chosen-film can be used to obtain laser at 1319nm.
