Abstract

Results of recent studies on highly charged Au ion generation, using the intense long pulses of the PALS high power iodine laser (λ=1.315 μm, EL =800 J400 ps), operating under variable experimental conditions (1ω, 3ω, varying target thickness and changing focus positions), are presented. Both the ion collectors and the ion electrostatic analyzers were applied for the identification of ions in a large distance from the target. The time-of-flight collector signals were treated by a means of peak deconvolution assuming a shifted Maxwell-Boltzmann form of the constituent ion current peaks. Attention was paid to the influence of pulse precursor, which becomes evident, especially, if using thinner targets and 1ω. The results for 3ω point to the presence of several groups of ions with the highest recorded charge state Au53+.
