Abstract: Ultrashort ultraviolet (UV) pulses are pivotal for resolving ultrafast electron dynamics. However, their efficient generation is strongly impeded by material dispersion and two-photon absorption, in particular if pulse durations around a few 10s of femtoseconds or below are targeted. Here, we present a new approach to ultrashort UV pulse generation: using the fourth harmonic generation output of a commercial ytterbium laser system delivering 220 fs UV pulses, we implement a multi-pass cell (MPC) providing 5.6 μJ pulses at 256 nm, compressed to 30.5 fs. Our results set a new short-wavelength record for MPC post-compression while offering attractive options to navigate the trade-off between up-conversion efficiency and acceptance bandwidth for UV pulse production.
