摘要：

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
