Time-Resolved Absorption/Reflectivity in VUV/HHG

Time-Resolved Absorption/Reflectivity in VUV/HHG

The high harmonic generation (HHG) source under development in the EFSL laboratory makes use of strongly non-linear processes in noble gases to generate high harmonics (up to 25th harmonic in Argon) by a three step process involving ionisation, electron acceleration and recombination. In the HHG set-up in EFSL laboratory the VUV light is monochromatised (probe) and combined with light from the OPA (pump) to perform UV-Vis/EUV pump-probe experiments with resolution of 100 fs.
