摘　　要：报道了一种LD泵浦的被动调QNd:LuVO4激光器,其中,Cr4+:YAG作为可饱和吸收体,KTP作为倍频晶体.在注入泵浦功率为7.4W时,得到的最大平均功率为0.88W,最高重复频率为27kHz,最窄脉宽为14ns的1.06μm基频激光输出.在泵浦功率为7W时,得到的脉冲绿光的平均功率为271mW,重复频率,脉宽,单脉冲能量和峰值功率分别为12.5kHz,28ns,21.7μJ和0.77kW.A passively Q - switched laser was reported by using Cr^4＋ ：YAG as saturable absorber and KTP as nonlinear crystal. When the incident pump power was 7.4W, the maximum average output power of 0.88W, the highest repetition rate of 27kHz and the narrowest pulse width of 14ns were obtained at 1.06μm. In pulsed green laser, the average output power of 271mW was realized at the pump power of 7W with the repetition rate of 12.5 kHz and pulse width of 28ns, and the pulse energy and peak power are 21.7μJ and 0.77kw, respectively.
