    摘要:

    以Cr4+:YAG为饱和吸收体,体布拉格光栅为耦合输出窗,研究了被动调Q闪光灯泵浦Nd:YAG单纵模激光器.通过扭转模腔和体布拉格光栅相结合的方式获得单纵模输出,提高了单纵模输出能量及稳定性.对于不同初始透过率的Cr4+:YAG晶体,得到了单纵模输出能量和脉宽的曲线.单纵模激光最大线宽约为78 MHz.最大单纵模单脉冲输出能量为20.8 mJ,最小的脉宽为13.2 ns,最大峰值功率为1.18 MW.

    Abstract:

    Taking Cr4+:YAGs as saturable absorbers and reflective volume Bragg gratings (RVBG) as output mirror, passively Q-switched operation of flash-lamp pumped Nd:YAG single-longitudinal-mode (SLM) laser was demonstrated. Single-frequency operation is accomplished for all output powers by twisted mode cavity and RVBG. This method can bring higher energy and stability. The maximum linewidth of SLM laser is about 78 MHz. The curve of energy and pulse width have been obtained under conditions of several Cr4+:YAGs with different initial transmissivity. The maximum SLM laser output energy is 20.8 mJ, minimum pulse duration is 13.2 ns and peak power is 1.18 MW.
