White Light Generation and Few Cycle Pulse Compression in Cascaded Multipass Cells
preprint
posted on 2023-01-10, 03:10 authored by Semyon Goncharov, Kilian Fritsch, Oleg ProninWe report supercontinuum generation and pulse compression in two stacked multipass cells based on dielectric mirrors. The 230 fs pulses at 1 MHz containing 12 $\mu$J were compressed by factor 33 down to 7 fs, corresponding to 1.0 GW peak power and overall transmission of 84 %. The source is particularly interesting for such applications as time-resolved ARPES, photoemission electron microscopy, and nonlinear spectroscopy.
