摘 要: | 实验所用激光系统由掺钕石榴石激光振荡器和三级钕玻璃放大器组成,输出光束达衍射极限.倍频晶体为KDP和KDP.用非聚焦的平行激光束倍频,最高获得了65%的能量转换效率.相应的峰值功率转换效率为84%左右.在低功率下.利用圆柱面透镜将激光束聚焦的办法使能量转换效率提高了8到30倍.用此方法最高能量转换效率达到了64%.

High efficiency laser frequency doubling |
| |
Abstract: | The laser system in our experiments consists of a Nd:YAG oscillator and three Nd:glass amplifiers with diffraction-limited output beams. Crystals for frequency doubling are KDP and KD*P. When unfocused collimated laser beams were used in frequency doubling, a maximum energy, conversion efficiency of 65% has been obtained,the corresponding peak power conversion efficiency was about 84%. In the case of low laser power, by means of cylindrical focusing laser beams, energy conversion efficiencies were increased by a factor of 8 to 30 with a maximum conversion efficiency of 64%. |
