This relationship between the density profile over path of ions and an ion current observed far from the ion source is based on a similarity relationship for ion currents with “frozen” charges observed at different distances from the target. In this contribution, we present distance-of-flight spectra of the charge density of ions emitted from various plasmas driven by a Compex 205 KrF excimer laser (λ=248 nm,τFWHM=23ns) which works at laser irradiances between 108 and 1010 W/cm2.
