Multipass cell for high-power few-cycle compression

Optics 2022-01-11 v1

Abstract

A multipass cell for nonlinear compression to few-cycle pulse duration is introduced comprising dielectrically enhanced silver mirrors on silicon substrates. Spectral broadening with 388 W output average power and 776 {\mu}J pulse energy is obtained at 82% cell transmission. A high output beam quality (M2<1.2) and a high spatio-spectral homogeneity (97.5%) as well as the compressibility of the output pulses to 6.9 fs duration are demonstrated. Finite element analysis reveals scalability of this cell to 2 kW average output power.
