摘要

In this work, influence of intense relativistic influence and plasma nonuniformity on ultrarelativistic laser beamfilamentation and filamentation instability has been investigated in homogeneous and inhomogeneous plasma. Theresults are shown that, in ultrarelativistic laser-plasma interaction, relativistic effect plays a crucial role on beamfilamentation and self-focusing, and plasma inhomogeneity further increases beam filamentation, while it alsostrengthens filamentation instability. To avoid filamentation instability, the research results show that it should try toreduce plasma inhomogeneity in laser-plasma interaction.
