二极管抽运Yb∶YAG陶瓷连续激光器和波长调谐实验研究
|
摘要
实验研究了二极管激光器抽运的国产Yb∶YAG陶瓷的高效率连续激光输出和波长调谐输出特性。比较了不同掺杂原子数分数(1%、2%、5%、10%、15%)和不同厚度(3、6 mm)的激光陶瓷的输出激光性质。当吸收抽运功率为6.3 W时,在3 mm厚15%掺杂样品中得到了2.4 W的连续激光输出功率,斜效率为47%。在谐振腔内插入三棱镜进行波长调谐,实验上得到的最宽波长调谐范围为1017~1095 nm。实验结果表明高质量的Yb∶YAG陶瓷在高功率全固态超短脉冲产生和放大中具有重要的应用。
The high efficiency continuous wave and wavelength tuning properties of a diode-pumped domestic Yb∶YAG ceramic laser is studied. The laser performances of ceramics with different atomic fractions(1%、2%、5%、10%、15%) and thickness(3、6 mm) are compared. The highest output power of 2.4 W is obtained from a 3 mm 15 %doping ceramic, pumped by an absorbed pump power of 6.3 W, corresponding to a slope efficiency of 47%.Wavelength tuning is realized by inserting a prism in the laser cavity, and the broadest tuning range is from 1017 to 1095 nm. The experimental results indicate the high-quality Yb∶YAG ceramic is a promising candidate in highpower all-solid-state ultrashort pulse generation and amplification.
