Abstract:   (10477 Views)
Self-focusing of an intense circularly-polarized laser pulse propagating through a magnetized non-maxwellian plasma is investigated. Based on a relativistic two-fluid model, nonlinear equation describing evaluation of slowly varying amplitude is obtained. The evolution of laser spot size is studied and effect of non-maxwellian distribution of charge density on the spot size is considered. It is shown that the existence of super-thermal electrons leads to the decreasing of the self-focusing quality.
