Performance of a liquid-nitrogen-cooled CW Tm, Ho:YLF laser 总被引：2，自引：0，他引：2
A liquid-nitrogen-cooled Tm, Ho:YLF laser is constructed with a 10-mm-long Tm(6%) and Ho(0.5%) co-doped yttrium lithium fluoride crystal pumped by a laser diode operating at 792 nm. The laser outputpower is improved by cooling the Tm, Ho:YLF crystal from 300 to 77 K. When the crystal is kept at 77K, the laser threshold pump power is 230 mW, the slope efficiency is 27.4%, and the maximum optical-to-optical efficiency is 19.9%. At the same time, the relation between the input power and the output powerat different temperatures is obtained. 相似文献
