We demonstrate pulse compressibility from 840 fs to 38 fs of 10 mJ pulses from a thin-disk amplifier at a repetition rate of 3 kHz after nonlinear broadening in a multipass cell. In addition, the temporal-intensity contrast is enhanced via nonlinear

Publikováno v: Optica High-brightness Sources and Light-driven Interactions Congress 2022.

We demonstrate nonlinear broadening of a Yb-doped thin-disk regenerative amplifier to the sub-30 fs, 60 mJ, 5 kHz regime. The broadening is performed via argon-filled multipass cell and compressibility to the Fourier limit is shown.

Multipass cell based spectral broadening of 100 mJ from a Yb-doped thin-disk amplifier at 5 kHz with compressibility to sub-45 fs

Autor: Y. Pfaff, G. Barbiero, M. Rampp, H. Wang, S. Klingebiel, C. Y. Teisset, R. Jung, A. H. Woldegeorgis, J. Brons, C. J. Saraceno, T. Metzger

Publikováno v: The International Conference on Ultrafast Phenomena (UP) 2022.

We report the multipass cell based nonlinear broadening of 100 mJ from a Yb-doped thin-disk regenerative amplifier at 5 kHz repetition rate and show its compressibility, close to the Fourier-transform limit, to 42 fs.
