摘要
利用Nd∶YAG/Cr∶YAG/YAG键合晶体,建立了具有高平均输出功率的LD侧面泵浦被动调Q激光器系统.当Cr∶YAG的初始透过率为85%、最大泵浦光功率为187.5 W时,1 064nm激光的平均输出功率为83.68W.通过KTP晶体进行倍频,在最大泵浦光功率下,产生了27.2W532nm绿光激光脉冲,同时脉冲宽度和重复频率分别为210ns和21.2kHz;绿光单脉冲能量和峰值功率分别为1.28mJ和6.1kW;泵浦光(808nm)到倍频光(532nm)的光-光效率为14.5%.
A high average power passively Q-switched LD side-pumped laser system at 1 064nm was set up by using Nd∶YAG/Cr∶YAG/YAG composite crystal.With 85%initial transmission of Cr∶YAG, the average output power of 1 064nm was measured.Under the maximum pump power of 187.5W,the maximum average output power of 83.68 W at 1 064nm was obtained.By frequency doubling the 1 064nm laser output in a KTP nonlinear crystal,27.2 W green laser pulses at 532nm with the corresponding pulse width of 210ns and the repetition rate of 21.2kHz were produced under the maximum pump power.The green laser single-pulse energy was 1.28 mJ and the peak power was 6.1kW.And the optical-to-optical conversion efficiency of pump light to frequency-doubling light was 14.5%.
