Abstract
We conducted high energy nonlinear broadening experiments based on a gas-filled multipass cell seeded by a Yb-doped thin-disk regenerative amplifier (Dira 1000-5) capable of delivering 200 mJ pulses at a repetition rate of 5 kHz with durations below 500 fs. This setup recently demonstrated the possibility to compress 180 mJ pulses down to 42 fs without affecting the beam quality, while increasing the peak power by a factor of 12. In this work, we further characterize the output in terms of compressibility and beam quality.
