We have recently demonstrated a simple power scaling procedure for Kerr-lens mode-locked thin-disk oscillators. Here we report on the extension of this scheme to a broadband high-peak-power thin-disk oscillator, delivering 140-fs pulses with a peak and average power of 62 MW and 155 W, respectively. This result shows that reaching the emission bandwidth of the gain material in Kerr-lens mode-locked thin-disk oscillators is feasible without sacrificing output power, efficiency, or stability by relying on high intracavity nonlinearities.
