摘　　要：利用新型实用的晶体材料V∶YAG作为被动调Q元件,实现了激光二极管泵浦Nd∶YVO4的1.34μm激光谱线调Q运转.研究了饱和吸收体小信号透过率对激光稳定性的影响,得出使用小信号透过率T0小的V∶YAG可使激光脉冲能量和重复频率稳定的结论.在1.6W的泵浦条件下,T0为96%、89%和85%时,4h脉冲能量和重复频率稳定性分别为15%、10%和5%.使用T0为85%的V∶YAG,获得了平均功率输出功率96mW,脉宽8.8ns,重复频率25kHz,峰值功率436W,脉冲能量3.84μJ的实验结果.A LD-pumped Nd ： YVO4 laser passively Q-switched at 1.34 μm by using V ： YAG which is a new type of crystal saturable absorber. The relationship between the stability of pulse laser and the small signal transmission of V ： YAG was studied. The results show the laser is stable when the V ： YAG with smaller signal transmission is used. When the pump power is 1.6 W, the stability of pulse energy and repetition rate for 4 hours is 15% ,10,5% for V ： YAG with small signal transmission of 96% ,89% ,85%,respectively. The results of average power of 96roW, minimum pulse width （FWHM） of 8. 8 ns, pulse repetition rate of 25 kHz,peak power of 436 W and pulse energy of 3.84 μJ were obtained for small signaltransmission of 85 %.
