Multi-filament structures in relativistic self-focusing
F. Cattani, A. Kim, D. Anderson, M. Lisak
Abstract
A simple model is derived to prove the multi-filament structure of relativistic self-focusing with ultra-intense lasers. Exact analytical solutions describing the transverse structure of waveguide channels with electron cavitation, for which both the relativistic and ponderomotive nonlinearities are taken into account, are presented.
