The interaction of clusters and nanodroplets (i.e., clusters with radii ≥ 10 nm) with ultraintense short near-infrared laser pulses (peak intensities IM=1014-1021 Wcm-2 pulse lengths τ = 10-250 fs, laser wavelength λ ≈ 800 nm) leads to extreme ionization, providing a tool to generate ultrahigh ion charges and kinetic energies [1-4]. Depending on the pulse parameters, first-row atoms can be completely ionized and for heavy elements like xenon up to 39 charges per atom can be achieved. Research goal is a theoretical description and modeling of these processes as well as the ion electron energetics and dynamics. (more…)
