High harmonic generation on noble gas clusters

Published on 2019-09-09T17:59:45Z (GMT) by
High order harmonics (HHG) were generated on noble gas cluster targets with different cluster sizes. The independently characterized cluster sources enabled the experimental investigation of the recombination process. HHG spectra were recorded for different backing pressures and gases (Ar, Xe) as a function of the driver pulse ellipticity. Since the ellipticity-dependent HHG decay agrees for the different gas-pressure pairs, we can conclude that the recombination process is dominated by atom-to-itself recollisions irrespective of the cluster size and material.
