在这封信中，我们提出了高功率连续波（CW）和Q开关飞秒激光写入Yb：YAG通道波导激光器。在Q开关操作中，通过半导体可饱和吸收镜（SESAM）获得，以及在CW操作中，激光器产生超过5.6 W的平均输出功率，并达到74%以上的斜率效率。该调Q激光器的最大重复频率为5.4MHz，最小脉冲宽度为11ns，最大脉冲能量为1 μ J，平均输出功率比以前报道的调Q通道波导激光器高近一个数量级。(C)2016美国光学学会
In this Letter, we present high-power continuous wave (CW) and Q-switched femtosecond laser-written Yb:YAG channel waveguide lasers. In Q-switched operation, obtained by a semiconductor saturable absorber mirror (SESAM), as well as in CW operation, the laser generates average output powers of more than 5.6 W and reaches slope efficiencies above 74%. The Q-switched laser operated at a maximum repetition rate of 5.4MHz with a minimum pulse duration of 11 ns, and with a maximum pulse energy of 1 mu J. This laser has almost an order of magnitude higher average output power than previously reported Q-switched channel waveguide lasers. (C) 2016 Optical Society of America
