利用885nm激光二极管直接抽运Nd:LGS实现了1.47W的1.06μm激光输出,光-光转换效率为17.9%,斜率效率为21.4%,光束质量因子M2在x和y方向分别为1.10和1.12。实验说明了Nd:LGS是一种优质的适于直接抽运的激光晶体。
The laser output of 1.06μm with Nd: LGS of 885nm was directly pumped at 1.47W. The light-to-light conversion efficiency was 17.9% and the slope efficiency was 21.4%. The beam quality factor M2 was 1.10 and 1.12 in the x and y directions, respectively. Experiments show that Nd: LGS is a good laser crystal suitable for direct pumping.
