Yb3+:Y2O3透明陶瓷激光器获得5 W连续激光输出
5 W CW Output Yb3+:Y2O3 Transparent Ceramic Laser
摘要
用带尾纤输出的激光二极管作为抽运源,采用端面抽运10% Yb3+∶Y2O3多晶透明陶瓷的方式获得了连续激光输出。抽运阈值功率为5.6 W,当陶瓷介质吸收的抽运功率为31.11 W时,Yb3+∶Y2O3多晶透明陶瓷获得了最大连续激光输出功率5.48W,光光转换效率为17.6%,斜率效率为25%。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,陶瓷的激光输出功率会得到进一步提高。这一研究成果表明,多晶透明陶瓷是一种非常有潜力的激光增益介质。
Abstract
CW laser output is obtained using laser diode end-pumped polycrystalline transparent 10% Yb3+∶Y2O3 ceramic. The pump threshold is 5.6 W, the maximum output power of 5.48 W is obtained with the absorbed pump power 31.11 W, and the slope efficiency is as high as 25%. At the same time there is no saturation in laser experiment, so the higher power output of Yb3+∶Y2O3 ceramic can be obtained with laser diode of higher power. Therefore Yb3+∶Y2O3 ceramic is a potential laser material.
