Influence of non-linearity of medium on the laser induced filamentation instability in magnetized plasma

Abstract

The effects of non-linearity of a medium on the growth rate of filamentation instability in a magnetized plasma interacting with an intense laser pulse is investigated. The non-linearity of the medium, modeled by Kerr non-linearity, is an important factor, which determines the rate of instability growth. The sensitivity of the rate of filamentation growth to the Kerr non-linear coefficient could be adjusted by the external magnetic field and the laser intensity. © 2018 Author(s).
