Using the Elettra storage-ring free-electron laser, we have implemented a light source generating sub-picosecond (ps) coherent optical pulses in the VUV spectral range. The setup relies on the frequency up-conversion of a high-power external signal (provided by a Ti:Sapphire laser) and makes use of a relativistic electron bunch as resonating medium. The produced VUV pulses have peak power in MW range, variable polarization, high shot-toshot stability and control of the timing parameters at the ps level.

Abstract

Using the Elettra storage-ring free-electron laser, we have implemented a light source generating sub-picosecond (ps) coherent optical pulses in the VUV spectral range. The setup relies on the frequency up-conversion of a high-power external signal (provided by a Ti:Sapphire laser) and makes use of a relativistic electron bunch as resonating medium. The produced VUV pulses have peak power in MW range, variable polarization, high shot-toshot stability and control of the timing parameters at the ps level. In this paper, we present the experimental layout, as well as the characterization of the temporal and spectral features of the emitted light. The radiation can be exploited for new experiments in the fields of dynamical phenomena, non-linear physics, magnetism and biology.
