摘要

飞秒环腔薄盘振荡器兼具高功率和单向与双向输出切换的灵活性。在此，我们报告了一种克尔透镜锁模的 Yb:YAG 环形腔薄盘振荡器，通过调整腔内器件的位置和参数，可在单向和双向操作之间进行切换。其平均功率和脉冲宽度分别接近 20 W 和低于 400 fs。此外，我们还进行了数值模拟，为寻找锁模区提供指导，并测量了双向脉冲的重复率，探索了环形腔中重复率差异的机理。这些结果为产生高功率近红外双光频梳以及开发中红外光频梳奠定了基础。

Kerr-lens mode-locked Yb:YAG ring-cavity thin-disk oscillator switchable between unidirectional and bidirectional operations

Femtosecond ring cavity thin disk oscillators combine high power with the flexibility switching output either unidirectionally and bidirectionally. Here, we report a Kerr lens mode-locked Yb:YAG ring cavity thin disk oscillator switchable between unidirectional and bidirectional operations by adjusting the position and parameters of the device in the cavity. The average power and pulse width of these are closing to 20 W and below 400 fs, respectively. Additionally, we present a numerical simulation to provide guidance for finding mode-locked regions and measure the repetition rates of bidirectional pulses, exploring the mechanism of the difference in repetition rates in the ring cavity. These results lay the foundation for generating a high-power near-infrared double optical frequency comb, as well as for the development of a mid-infrared optical frequency comb.
