This paper reports on nonlinear spectral broadening of 1.1 ps pulses in a gas‐filled multi‐pass cell to generate sub‐100 fs optical pulses at 1030 nm and 515 nm at pulse energies of 0.8 mJ and 225 µJ, respectively, for pump–probe experiments at the free‐electron laser FLASH. Combining a 100 kHz Yb:YAG laser with 180 W in‐burst average power and a post‐compression platform enables reaching simultaneously high average powers and short pulse durations for high‐repetition‐rate FEL pump–probe experiments.
