摘　　要：为获得高重频、高增益的355nm紫外激光输出,利用Nd∶YVO4激光晶体、端面泵浦LD和声光Q开关,设计了腔内三倍频V型谐振腔结构,在不同Q开关重复频率下,测试分析了激光功率和脉冲宽度的变化。对激光器参数进行了优化,当LD泵浦电流为9.4A时,355nm紫外激光最高输出平均功率达到了5.38W,脉冲宽度最窄为17.5ns,激光重复频率为30kHz。In order to obtain the output of high-repetition-rate and high efficient power of 355nm ultraviolet laser,Nd∶YVO4 laser crystal and LD side-pumped acoustic-optic Q-switched were used,the configuration of V-shaped with frequency tripling resonant cavity was designed.At different Q-switch repeat frequencies,the changes of laser power and pulse width were analyzed.The laser parameters are optimized,when the LD pump current is 9.4A,the maximum output power of the 355nm UV laser reaches 5.38W,the pulse width is 17.5ns,and the laser repeat frequency is 30kHz.
