Paper Abstract

High energy electron jets are produced by the interaction of high-intense laser pulse with various density plasmas. With t e progress of short-pulse multiterawatt laser, it has become possible to produce MeV electron in a plasma. These electrons can be used to apply fusion energy research, particle acceleration, and x-ray source development. 3D particle-in-cell simulations were performed to produce supra thermal electrons. We studied the interaction of P-polarized shaped laser pulse with solid foil targets. In this case an interaction of a main part of laser pulse extremely enhanced energy of fast escaped electrons at some conditions. Proposed mechanism of electron acceleration by laser wave in such plasmas raises electron energy up to 10 MeV for laser intensity more than 1019W/cm2. Conversion coefficient of laser energy to electron one strongly depends on laser intensity.
