Relativistic self-focusing in underdense plasma

PDF Version Also Available for Download.

Description

In the present paper, we discuss light self-focusing in underdense (n<n{sub c}) plasmas. We will show that ion motion is important even for picosecond pulse durations and a description of relativistic self-focusing including ion dynamics will be presented in second part of the paper. In particular, we will demonstrate the formation of empty, wide channels in underdense plasma in the wake of the laser pulse. we discuss the applicability of our results to real situations and possible consequences for the ``Fast Ignitor`` project.
