摘　　要：报道了利用激光二极管端面抽运Nd∶YAG晶体,通过Cr4+∶YAG晶体可饱和吸收被动调Q,KTP晶体腔外倍频及BBO晶体腔外四倍频,实现266 nm连续脉冲输出。简要分析了被动调Q基本原理,计算并模拟了1064 nm基频光在理想状态下Cr4+∶YAG晶体不同初始透过率对脉冲激光单脉冲能量的影响。LD抽运功率为4.8 W时,得到266 nm紫外激光平均输出功率为5.63 mW,单脉冲能量约为0.5μJ。在紧凑型毫瓦级266 nm激光器实用化方面取得了一定进展。266 nm ultraviolet pulse laser is achieved by KTP crystal extra-cavity frequency doubling and BBO crystal extra-cavity frequency quadrupling of a laser in Nd ∶YAG end-pumped by LD and passively Q-switched by Cr4＋∶YAG.The basic principle of passively Q-switched is analyzed,and the influence of the initial transmission of the Cr4＋∶YAG on single pulse energy of the 1 064nm laser under the ideal condition is calculated and simulated.When the pump power is 4.8W,the output power of 5.63mW and single pulse energy of 0.5μJ at 266 nm laser is ob-tained.Certain progress of practicability of compact milliwatt levels 266nm laser has been made.
