We present a high-power, high-efficiency and low threshold laser prototype based on doped ceramic Yb(3+):YAG. We achieved an output power of 9 W with a slope efficiency of 73% and a threshold of 1 W at 1030 nm in quasi-Continuous Wave (QCW). Moreover, we obtained an output power 7.7 W with a slope efficiency of 60% in Continuous Wave (CW). Finally, a characterization of a low losses tunable cavity for several laser wavelengths with an output power exceeding 5 W is reported.
我们展示了一种基于掺杂陶瓷Yb(3+):YAG的高功率、高效率和低阈值激光原型。在准连续波（QCW）模式下，我们在1030nm处实现了9W的输出功率，斜率效率为73%，阈值为1W。此外，在连续波（CW）模式下，我们获得了7.7W的输出功率，斜率效率为60%。最后，报道了一种用于几种激光波长的低损耗可调谐腔的特性，其输出功率超过5W。
