Abstract :
This study investigates a mode-locked Yb:YAG thin-disk laser oscillator with self-imaging active multipass cell and large output coupling rates for a suppression of nonlinear optical effects.The experimentally generated pulse energies of more than 25 muJ at sub-picosecond pulse length of 928 fs are believed to be the highest ever obtained directly from an ultrafast laser oscillator without further amplification stages. Stable single pulse operation in ambient atmosphere is obtained with this system, with average output powers above 76 W at a repetition rate of 2.93 MHz.
