X-ray radiation of clusters irradiated by ultrafast, high-intensity laser pulses.
High resolution x-ray emission spectra of plasma created by laser irradiation of rare-gas (Ar, Kr, Xe) clusters have been measured at laser intensities over 10[sup 19] W/cm[sup 2] and 30-fs laser pulses. To make these measurements possible, micron-size clusters were produced using a specially designed conical nozzle and prepulse intensities were decreased using Pockels cell switches. The Boltzmann equation and a detailed collisional radiative model are solved simultaneously as a function of time to model the time integrated x-ray spectra of the transient plasma produced by a high intensity ultrafast laser pulses. The results are quantitatively in good agreement with the experimentally observed x-ray emission spectra of Ar clusters.
