摘　　要：利用半导体激光器(LD)端面泵浦YVO4/Nd∶YVO4键合晶体,实现声光调Q1064nm的窄脉宽激光输出。从理论和实验上分析了泵浦功率和重复频率对输出调Q脉宽的影响。在泵浦功率为20W情况下,重复频率为2kHz时,获得最短脉冲宽度为16.4ns;重复频率为40kHz时,获得了最大平均输出功率为6.9W,光-光转换效率为34.5%。A acousto-optics Q-switched 1064nm short pulse width laser was repoited,used LD end-pumped YVO4/Nd： YVQ bonding crystal. The effects of pumped power and pulse repetition rat on pulse width are analyzed from theory and experiment. At the pump power of 20W and the repetition rate of 2kHz, we get the shortest pulse width of 16.4 ns;at the repetition rate of 40kHz,the highest average output power 6.9W have been obtained, and the optics-optics conversion efficiency is 34.5%.
