HHG

High Armonic Generation (HHG)

EFSL - EuroFEL Support Laboratory  -

 
The high harmonic generation (HHG) source under development in the 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 this 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. The monochromator was developed in collaboration with CNR-IFN.
