| 摘 要： | 报道了一种激光二极管(LD)端面泵浦10at%掺杂Yb:YAG激光晶体(4×4×1mm)和Ⅰ类临界相位匹配LBO的腔内倍频全固态绿光激光器.为了克服"绿光问题",采用了两个激光二极管偏振耦合系统.在双路泵浦功率为1.2W时,获得最高功率为40mW525nm的连续基模激光输出.在腔内插入Cr4+:YAG饱和吸收体被动调Q,在泵浦功率为1.2W时,可以获得平均功率为5.2mW,脉冲重复频率为2.44kHz,脉冲宽度为51.5ns,峰值功率为41.7W的515nm脉冲激光输出.输出波长发生变化,而且515nm脉冲激光输出的阈值仅为728mW.

| Abstract: | A laser diode end-pumped 10at% doped Yb:YAG microchip crystal intracavity frequency doubled all solid-stated green laser was reported.In order to overcome the problem of green problem of SHG,two polarization-coupled laser diodes system were used.With the pump power of 1.2 W,40 mW TEM00 continuous wave laser at 525 nm was obtained,and the optical conversion efficiency is 3.3%.When inserting Cr4+:YAG crystal with 98% low-power transmission in the resonator,the maximum output power of 5.2 mW,pulse duration wid... |
