A Kerr-lens mode-locked (KLM) Yb:YAG thin-disk oscillator delivering 215-fs pulses with 75-W average power and 1.4-MW peak power at a repetition rate of 260 MHz is presented. Self-starting KLM is demonstrated at an output power of 68 W. This is the highest repetition rate of any mode-locked thin-disk oscillators so far. Concepts for scaling the repetition rate up to 1 GHz are discussed.
介绍了一种克尔透镜锁模（KLM）Yb:YAG 薄片振荡器，其在 260 MHz 的重复频率下，能产生脉宽为 215 fs、平均功率为 75 W、峰值功率为 1.4 MW 的脉冲。在输出功率为 68 W 时实现了自启动 KLM。这是迄今为止所有锁模薄片振荡器中最高的重复频率。文中还讨论了将重复频率扩展至 1 GHz 的相关概念。
