Abstract

A tightly focused laser pulse with relativistic intensity propagating in a dense plasma is studied by means of 2D particle-in-cell simulation. The results demonstrate that the laser propagation in the plasma is strongly dependent on the laser focus position. It is found that the laser can penetrate deeper in the plasma and create an on-axis plasma channel at certain focus positions, which is due to the suppression of the filamentation instability in the laser plasma interactions. The results are of interest for understanding of the fast ignition related experiments.
