摘要：
The possibility of electron acceleration during the laser radiation relativistic and charge-displacement self-channeling is studied theoretically. A new acceleration mechanism related to the formation of an ion cloud traveling in matter with the laser pulse (due to the effect of the ponderomotive force) is considered. The quasistationary electric and magnetic fields generated by the moving ion cloud can accelerate electrons to energies of tens of MeV and result in the formation of an electron beam going forward coaxially with the laser pulse. The angular distribution of accelerated electron calculated matches the experimental results found in the available publications. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
