摘　　要：报道了薄片式Yb…YAG/1030nm激光器,Yb…YAG晶体掺杂原子数分数为10%,几何尺寸Φ11mm×420μm,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26mm,曲率半径50mm,在32.4W抽运功率下,1030nm最高输出可达13.55W,光光转换效率为41.8%。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%.
