Efficient energy absorption and the emission of highly charged atomic ions are well known effects emerging from the interaction of ultrashort and intense near-infrared laser pulses with clusters. Besides the many corresponding, relatively well understood experiments on free clusters, the influence of a superfluid environment has not been worked out in detail yet. For a theoretical study of the matrix effects on the absorption and ionization processes we use a semiclassical molecular dynamics approach. Results on the spatially resolved energy absorption as well as on final ion charge spectra for dual-pulse excitation of XeN@HeM as function of laser intensity and size of the matrix will be presented. |
