我们报道了二极管泵浦的Er3+:Y2O3陶瓷激光器，在~2.7 μm下具有~ 14w的真连续波输出。这表明，相对于以前使用这种激光材料的最佳结果，功率增加了近十倍。我们还认为，这是迄今为止报道的在~3 μm波长范围内工作的掺Er3+块状晶体激光器的最高功率。974 nm泵浦Er3+:Y2O3激光器实现了功率缩放性能，斜率效率为~26%。
We report diode-pumped Er3+:Y2O3 ceramic laser with ~14 W of true CW output at ~2.7 μm. This presents nearly ten-fold power increase with respect to previous best result with this laser material. We also believe this to be the highest power ever reported from Er3+ -doped bulk crystalline laser operating in a ~3-μm wavelength range. Power-scaled performance of 974-nm pumped Er3+:Y2O3 laser was achieved with the slope efficiency of ~26%.
