We report the operation of a diode-pumped monolithic self-Q-switched Cr,Nd:YAG laser in which the codoped ions create saturable absorption for Nd(3+) laser emission at 1064 nm. With a 70-microm beam diameter in the gain medium, the Q-switched pulse has a duration of 3.5 ns and a peak power of 2 kW. The output is linearly polarized with an extinction ratio of 600:1. The pulse-to-pulse intensity fluctuation is less than the instrument resolution of 0.25%. A 5-mm-long KTP crystal butted against the monolithic cavity produces 2-ns-long pulses at 532nm with a peak power-conversion efficiency of 30%.
我们报道了一种二极管泵浦的单片自调Q Cr,Nd:YAG激光器的运行情况，其中共掺杂离子为1064nm的Nd(3+)激光发射产生可饱和吸收。在增益介质中光束直径为70微米时，调Q脉冲的持续时间为3.5纳秒，峰值功率为2千瓦。输出为线偏振，消光比为600:1。脉冲间强度波动小于仪器分辨率0.25%。一块与单片腔对接的5毫米长KTP晶体在532nm处产生2纳秒长的脉冲，峰值功率转换效率为30%。
