Transport in a laser irradiated thin foil
Abstract
Three dimensional Particle-In-Cell simulations describing the interaction of a short intense laser pulse with thin foils are presented. It is observed that the laser generated electron current decays into magnetically isolated filaments. The filaments grow in scale and magnitude by reconnection. Two different laser wavelengths are considered. The spatial separation of the filaments varies for the two wavelengths. Many current filaments carry net electric currents exceeding the Alfven current considerably.
