High-order harmonic generation (HHG) is currently utilized for developing compact table-top radiation sources to provide highly coherent extreme ultraviolet (XUV) and soft X-ray pulses; however, the low repetition rate of fundamental lasers, which is

We demonstrated intra-cavity high harmonic generation (HHG) in a Yb:YAG thin disk mode-locked oscillator with a repetition rate of 3MHz. Two HHG ports are simultaneously operated in a single mode-locked oscillator.

We have generated 1-mJ pulses with a pulse duration of 520 fs at a repetition rate of 2.85 MHz in a mode-locked oscillator cavity. These pulses can be used for generating high-harmonics in the cavity.
