本文报道了一种100 μm短扩散键合二极管泵浦Yb：YAG矩形通道波导的激光性能。使用一个端泵浦配置引导慢轴，泵浦模式和非引导谐振器模式的高重叠实现。在两个60 μm宽条二极管抽运4W的情况下，获得了0.7W的近衍射极限输出。
We report the laser performance of a short diffusion-bonded diode-pumped Yb:YAG rectangular channel waveguide of 100 μm cross section. Using an end-pumped configuration guiding only the slow axis, a high overlap of the pump mode and the nonguided resonator mode is achieved. With 4 W of pump power from two 60 μm high-power broad-stripe diodes, 0.7 W of output power with nearly diffraction-limited performance is obtained.
