Abstract

We report a diode-pumped passively Q-switched Nd:LuVO4 laserat 1.34 microm using V3+:YAG as saturable absorber. The characteristics of a-cut and c-cut Nd:LuVO4 passive Q-switching operation were studied. The average output power of 1.02 W was obtained under the pump power of 12.88 W, corresponding to the optical conversion efficiency of 8% and slope efficiency of 10% in c-cut Nd:LuVO4 laser. The maximum pulse energy of 17.6 microJ and the highest peak power of 820 W were obtained at pulse width of 21 ns and pulse repetition rate of 22.4 kHz in a-cut Nd:LuVO4 laser.

摘要

我们报道了一种采用V3+:YAG作为可饱和吸收体的二极管泵浦被动调Q 1.34微米钕:钒酸镥激光。研究了a切和c切钕:钒酸镥被动调Q运转的特性。在12.88瓦的泵浦功率下，c切钕:钒酸镥激光器获得了1.02瓦的平均输出功率，对应的光转换效率为8%，斜率效率为10%。在a切钕:钒酸镥激光器中，在脉冲宽度为21纳秒、脉冲重复频率为22.4千赫兹时，获得了17.6微焦的最大脉冲能量和820瓦的最高峰值功率。
