High-power 2 μm lasers are promising candidates for a variety of applications including remote sens- ing, wind lidar, and medicine as well as mid- infrared generation via pumping of optical parametric oscillators. Due to the advantages of low quantum defects and high efficiency, resonantly pumped Ho- doped lasers have attracted great attention. Ho：YAG single crystals have also been widely studied to ob- tain cw and Q-switched laser operation in the 2 μm wavelengths range. 相似文献

对注入有源Fabry-Perot腔内的单纵模脉冲进行了延时理论分析, 计算了Fabry-Perot腔内增益, 并对脉冲输出进行了数值模拟, 结果表明当脉冲能量衰减到一定值时, 新增抽运粒子数提供的增益可以补偿腔内损耗, 延时脉冲的输出可以达到稳态. 然后利用激光二极管侧面抽运Nd: YAG激光器做为Fabry-Perot腔, 对外部入射的单纵模脉冲光进行了延时, 得到了延时时间2 μups、脉冲数量140个的实验结果. 最后利用有源Fabry-Perot腔对参考光进行延时, 声光移频器对信号光产生频移, 进行了外差实验, 实验结果与移频器的设置值相符, 误差在4%以内. 相似文献
