Abstract
We discuss multipass cell based nonlinear broadening experiments between 60 mJ and 150 mJ pulse energy from a Yb-doped thin-disk regenerative amplifier at 5 kHz repetition rate. Moreover, the compressibility to the Fourier transform limit of each experiment, to sub-40 fs or even sub-30 fs, is shown.
