摘要
报道了薄片式Yb:YAG/1030 nm激光器，Yb:YAG晶体掺杂原子数分数为10%，几何尺寸Φ11 mm×420 μm，高反面经Cr/Au金属化处理后，采用铟焊工艺焊接到微通道水冷热沉上。耦合系统为四程抽运结构，球面镜规格为直径26 mm，曲率半径50 mm，在32.4 W抽运功率下，1030 nm最高输出可达13.55 W，光光转换效率为41.8%。
Abstract
The laser-diode-array (LDA) pumped Yb:YAG thin-disc 1030 nm laser is demonstrated. The Yb:YAG crystal doped with 10% Yb atomic fraction is 420 μm in thickness and 11 mm in diameter. It is mounted onto the micro-channel copper heat sink by Cr/Au/In. The four-pass optical coupling system is well designed with two spherical imaging mirrors (diameter 26 mm, radius of curvature 50 mm). With 32.4 W pump power, the maximum output power of 13.55 W at 1030 nm is obtained. The optical-optical conversion efficiency is 41.8%.
