Abstract
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.
