报道了一种高效率的2微米带内泵浦的Ho：YAG激光器。谐振器包括两个Ho：YLF晶体，每个晶体由两个正交偏振的二极管泵浦的Tm：YLF激光器双端泵浦。最大连续波输出功率为103W，对应的斜率效率为67.8%，光-光转换效率为63.5%。在调Q模式下，获得了101W的30 kHz激光输出，对应的斜率效率为66.2%。光束质量或M-2因子被发现小于2。(C)2012年美国光学学会
An efficient 2 mu m in-band pumped Ho:YAG laser was demonstrated. The resonator involves two Ho:YAG crystals, each of which was dual-end-pumped by two orthogonally polarized diode-pumped Tm:YLF lasers. The maximum continuous wave output power of 103 W was achieved, corresponding to a slope efficiency of 67.8% with respect to the incident pump power and an optical-to-optical conversion efficiency of 63.5%. Under Q-switched mode, we obtained 101 W laser output at 30 kHz, corresponding to a slope efficiency of 66.2%. The beam quality or M-2 factor was found to be less than 2.
