Ultrafast Deep and Vacuum Ultraviolet Gas-Filled Hollow-Core Fibre Sources for Time-Resolved Photoelectron Spectroscopy

Abstract

We demonstrate time-resolved photoelectron velocity-map imaging using tunable DUV pulses generated through resonant dispersive-wave emission in gas-filled photonic-crystal fibres, and explain the potential of this source for time-resolved ultraviolet spectroscopy of molecules and condensed-matter physics.
