Description

Results of systematic studies of laser-produced multiply charged ions are summarized. Experiments were performed using the iodine laser system PERUN operating with the fundamental frequency (λ=1.315 μm) and its 2nd (λ=0.657 μm) and 3rd (λ=0.438 μm) harmonics. Short laser pulse (350 ps) and a focus spot diameter of 100 μm allowed for the laser power densities in the range of 5x1013-1.5x1015 W/cm2. Different medium- and high-Z elements were tested as a target. Corpuscular diagnostics were based on a time-of-flight method. The ions with maximum charge state around 50+ and having energy higher than 4 MeV were registered for Ta, W, Pt, Au, Pb, Bi in a distance of about 2m. Correlation of X-ray radiation and ion generation was examined. The occurrence of highly charged ions in the far expansion zone is ascribed to the mechanism of charge distribution 'freezing' during a two temperature plasma expansion
