激光二极管抽运10at.-%Yb:YAG晶体获得高效连续激光输出
LD Pumped 10at.-% Yb:YAG Laser with High Efficiency CW Output
摘要
用激光二极管作为抽运源, 在室温下获得了Yb:YAG晶体的连续激光输出, 抽运的阈值功率较低为2.2 W, 当入射到晶体上的抽运功率为18 W时,Yb:YAG晶体微片获得了最大连续激光输出功率为5.2 W,斜率效率为33%。同时在激光实验过程中, 没有发现饱和现象,因此采用更高功率的激光二极管作为抽运源, 晶体的激光输出 功率将会得到进一步的提高。这一研究对于实现Yb:YAG晶体的高功率激光输出具有重要意义。
Abstract
Using laser diode (LD) as pumping source, CW Yb:YAG laser output was obtained at room temperature. The pumping threshold of Yb:YAG is as low as 2.2 W, the maximum output power of 5.2 W was attained with the pumping power of 18 W, and slope efficiency is as high as 33%. At the same time there is no saturation in laser experiments, so the high power output of Yb. YAG laser can be obtained with high power diode laser pumping source. This research will be beneficial to the development of high power Yb:YAG lasers.
