摘要
介绍了在室温条件下双端抽运高功率Tm:YAP板条激光器。采用双凹腔结构通过优化泵浦光斑尺寸,在腔内插入双FP标准具控制激光波长,当抽运功率为164.4 W时,获得了54.7 W的连续输出功率,其斜率效率为44.2%,输出波长为1 938.8 nm,随着功率的增加输出波长只有0.3 nm的漂移,且实现了0.18 nm窄线宽的激光输出,同时测量了10 W、25 W和35 W时的光束质量,分别为3.5、4.1和4.2。
A Tm：YAP slab laser with double-end-pumped and high power under room temperature is intro- duced. With double concave cavity structure and optimizing pumping facula size, F-P etalon is inserted in the cav- ity to control laser wavelength. When pumped power is 164.4 W, 54.7 W continuous output power is obtained, the slop efficiency is 44.2% and the output wavelength is 1 938.8 nm. With the increasing of the power, the out- put wavelength only has 0.3 nm shift and the laser output for 0.18 nm narrow line width is realized. And the opti- cal beam quality is measured when pumped power is 10 W, 25 W and 35 W, which is 3.5, 4.1 and 4.2 respectively.
