Highly efficient Q-switched Yb:YAG channel waveguide laser with 5.6W of average output power
In this Letter, we present high-power continuous wave (CW) and super(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...

| description | In this Letter, we present high-power continuous wave (CW) and super(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 5.4 MHz 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. |
