A Kerr-lens mode-locked (KLM) thin-disk laser with Yb:LuAG ceramic was demonstrated. Yb:LuAG ceramic is an attractive material for high-power lasers due to its high thermal conductivity and large emission cross section. The highest output power of 17 W with a pulse duration of 130 fs was achieved. Moreover, the pulse duration of 88 fs was also obtained with a high-Q factor cavity. To the best of our knowledge, this is the first demonstration of a KLM thin-disk laser based on Yb:LuAG, including both ceramic and single crystal. The results show the usefulness of ceramic thin disks for high-power ultrashort pulse laser sources.

Kerr-lens锁模Yb：LuAG陶瓷薄盘激光器

演示了具有Yb：LuAG陶瓷的Kerr透镜锁模（KLM）薄盘激光器。Yb：LuAG陶瓷因其高导热率和大发射截面而成为大功率激光器的诱人材料。在130 fs的脉冲持续时间内实现了17 W的最高输出功率。此外，在高Q因子腔中也可获得88 fs的脉冲持续时间。据我们所知，这是基于Yb：LuAG的KLM薄盘激光器的首次演示，包括陶瓷和单晶。结果表明，陶瓷薄盘对于大功率超短脉冲激光源很有用。
