【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。更多还原

【Abstract】 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 pulsedwidth of 17ns and divergence of 2.7mrad were acquired.Experimental results show that coating chosen-film can be used to obtain laser at 1319nm.更多还原
