Charge state selective double color landscapes of highly charged ions from clusters exposed to intense laser pulses — •Truong Nguyen Xuan, Josef Tiggesbäumker, and Karl-Heinz Meiwes-Broer — Institut für Physik, Universität Rostock, 18055 Rostock

We use the pulse shaping technique to investigate the interaction of intense femtosecond laser fields with embedded clusters. Colored double-pulses are used to systematiclly study the dependence of the extreme charging on the pulse energy, the pulse separation as well as the pulse intensity ratio. The prepulse intensity thresholds which have been extracted been extracted from the data show as remarkably low values which are nearly constant irrespective of the chosen charge state.
