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.

We study the limiting dynamics of C 60-doped porous sol-gel glasses by single- and double-pulse pump-probe experiments. We find that, contrary to crystalline films of C60, reverse saturable absorption (RSA) of these solid samples can be described by a 5-level model developed for C 60-solutions. We observe an ultrafast rise time, a large transmission-decrease at high fluence, a shortened singlet-state lifetime as compared to solutions, but nevertheless an important triplet yield. We explain differences with respect to solutions by the absence of stabilizing aromatic solvents and by the interaction of the amorphous environment with the molecules, broadening considerably the spectral features of RSA.
