Theoretical investigation on novel particle beams and radiation sources in relativistic laser-solid interactions

Abstract

We report the recent theoretical and numerical studies of quasi-monoenergetic electron and proton beams in laser solid interactions, where the quasi-monoenergetic electrons are produce in laser interaction with wire-targets and the quasi-monoenegetic protons are produced by ultra-intense circularly polarized laser pulses in a new acceleration regime called phase-stability acceleration. For the generation of coherent radiation at high frequencies, attention is paid on the emission from electron plasma waves excited in a thin solid target.
