Transformation of Laser Radiation into Coherent Structures and Fast Charged Particles
Abstract
With 2D PIC simulations we show that during the interaction of a high intensity ultra short laser pulse with a collisionless plasma in the wake of the laser pulse electromagnetic relativistically strong solitons are formed, which evolve asymptotically into post-solitons. A post-soliton is a slowly expanding cavity in the ion and electron densities which traps electromagnetic energy. Fast ions are accelerated during the post-soliton formation. Post-solitons are elementary components of relativistic electromagnetic turbulence in laser irradiated plasmas. The long time evolution of post-solitons in homogeneous and inhomogeneous plasma slabs is investigated. The spectra of the e.m. energy and the distributions of the fast particles transmitted through the plasma slab are analysed.
