Probing the cluster dynamics with atto-second XUV laser pulses — •Ionuţ Georgescu, Ulf Saalmann, and Jan-Michael Rost — Max-Planck-Institut für Physik komplexer Systeme, Nöthnitzerstr. 38, 01187 Dresden, Germany
Xenon clusters have been exposed to short intense laser pulses at 98nm wavelength within the first testing stages of the upcoming X-Ray Free Electron Laser at DESY, Hamburg. The experiment [1] has shown an unexpectedly effective energy absorption mechanism resulting into Coulomb explosion of the clusters with high measured ionic charge states.
Several theoretical models [2-5] have managed to explain the outcome of the
experiments, but they all disagree on the internal mechanisms of the energy
absorption. We propose here a pump-probe scheme with atto-second XUV laser
pulses which would offer a time resolved picture of the transient ionic charge
states in the cluster.
