Effects of Electron Self-Force on Superstrong Laser Pulse

ORAL

Abstract

We analyze the effect of self-force on a single electron and on plasma electrons giving attention to the electromagnetic energy generated by an accelerated motion in a field of a relativistically strong electromagnetic wave. The effect is essential if the scattered energy is comparable with the rest-mass energy of the electron in the frame of reference where the electron was initially at rest. We develop a method for solving the Lorentz-Abraham-Dirac equation and accounting for radiation in a self-consistent manner. The solution is then applied to the interactions of super-strong laser fields with an electron and a plasma layer including the presence of strong charge separation fields. This scheme allows a simulation of resulting radiation with spatial and spectral distributions. We consider a conversion efficiency of incident radiation to $\gamma $-ray emission at intensities of 10$^{22}$ - 10$^{24}$ W/cm$^{2}$.
