摘要
报道了采用半导体激光器(LD)单端泵浦Nd∶GdVO4晶体,在谐振腔内同时利用声光器件、Cr4+∶YAG晶体,实现1.06μm激光的双调Q运转。当泵浦功率为7.7W,重复频率为10kHz时,得到最短脉冲宽度20ns,单脉冲能量45.8μJ及相应峰值功率2.29kW的激光脉冲。
Using both acoustic-optic Q-switcher and Cr^4+:YAG crystal,a LD-end-pumped double Q-switched Nd:GdVO4 laser at 1.06μm is reported.At the pump power of 7.7 W and the repetition rate of 10 kHz,the shortest pulse width of 20ns,the single pulse energy of 45.8μJ and the highest peak power of 2.29 kW are achieved,respectively.
