Single-shot electron imaging of dopant-induced nanoplasmas
Abstract: We present single-shot electron velocity-map images of nanoplasmas generated from dopedhelium nanodroplets and neon clusters by intense near-infrared and mid-infrared laser pulses. Wereport a large variety of signal types, most crucially depending on the cluster size. The commonfeature is a two-component distribution for each single-cluster event: a bright inner part withnearly circular shape corresponding to electron energies up to a few eV, surrounded by anextended background of more energetic electrons. The total counts and energy of the electrons inthe inner part are strongly correlated and follow a simple power-law dependence. Deviations fromthe circular shape of the inner electrons observed for neon clusters and large helium nanodropletsindicate non-spherical shapes of the neutral clusters. The dependence of the measured electronenergies on the extraction voltage of the spectrometer indicates that the evolution of thenanoplasma is significantly affected by the presence of an external electric field. This conjecture isconfirmed by molecular dynamics simulations, which reproduce the salient features of theexperimental electron spectra
