摘要
1319 nm激光处在大气透过窗口、光纤低损耗和接近零色散区域, 在很多领域有着广泛的应用。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1064 nm等其他波长的起振, 最终实现1319 nm激光单脉冲输出。实验得到1319 nm激光静态输出能量340.9 mJ, 动态输出76.8 mJ, 重复频率1 Hz, 脉宽17 ns, 束散角2.7 mrad。结果表明, 通过镀制高选择性介质膜的方法可以实现1319 nm激光调Q脉冲输出。
Abstract
1319 nm waveband sets in the window of air transparency and the low lossness of fiber, and it approaches to zero dispersion. It has been widely used in many fields, and has attracted much attention. The transition radiation energy level of the 1319 nm is analyzed. The critical technology of restraining resonance of 1064 nm so as to improve that of 1319 nm is discussed. A pulsed output static energy of 340.9 mJ at 1319 nm, Q-switched output energy of 76.8 mJ with pulsed-width of 17 ns and divergence of 2.7 mrad are acquired. Experimental results show that coating chosen-film can be used to generate the laser at 1319 nm.
