摘　　要：报道了连续二极管端面泵浦2 μm高重复频率Tm,Ho:YLF激光器的实验研究结果.792 nm光纤耦合激光二极管作泵浦源,泵浦液氮制冷的Tm,Ho:YLF晶体.动态运转时,平均输出功率达到4 W,相应的能量抽取效率大于85%.采用声光调Q方式,重复频率1～50 kHz可调,10 kHz时,峰值功率达到12 kW,最小脉宽为32 ns.同时,还对二极管泵浦2 μm激光器设计中的各种因素进行了分析.A CW LD end pumped high pulsed repetition rate （PRF） Tm, Ho：YLF laser was reported. The fiber-coupled laser diode of 792 nm as a pumping source pumped the liquid-nitrogen-cooled Tm, Ho： YLF crystal. The average output power of 4 W was obtained and extraction efficiency was more than 85% in dynamic running. The PRF varied from 1-5 0 kHz by using an A-O Q-switch. The peak power of 12 kW and pulse width of 32 ns were achieved at PRF of 10 kHz. At the same time several important factors in the 2μm laser design were analyzed.
