Few-cycle pulse generation by double-stage hybrid multi-pass multi-plate nonlinear pulse compression

Viotti, Anne-Lise; Li, Chen; Arisholm, Gunnar; Winkelmann, Lutz; Hartl, Ingmar; Heyl, Christoph M.; Seidel, Marcus (2023-02-10)

Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers are used which, however, cannot directly ...
Ultrafast Pulse Compression in Bulk with > 20 Times Spectral Broadening Factor from a Single Stage

Seidel, Marcus; Balla, Prannay; Arisholm, Gunnar; Winkelmann, Lutz; Hartl, Ingmar; Heyl, Christoph M. (2021-11-01)

We introduce the combination of multi-pass cell and multi-plate spectral broadening. We demonstrate the compression of 110-μJ pulses from 900-fs to 60-fs in a single stage and report broadening to 38-fs transform-limit by ...
