Study of QED effects in collision of near-surface accelerated electrons with high-intensity lasers — •Marko Filipovic, Christoph Baumann, and Alexander Pukhov — Institut für Theoretische Physik I, Heinrich-Heine-Universität, Düsseldorf, Germany

As the development of laser technology progresses, ever higher intensities and better beam qualities in laboratories become available. This advance enables new experimental setups in the study of laser-plasma interaction and quantum electrodynamic (QED) effects like quantum photon emission and pair production in extreme fields and densities.

We present two-dimensional Monte-Carlo particle-in-cell simulations of two high-intensity lasers grazing the surface of a solid-state target. Due to the fields near the target surface electrons are extracted and accelerated. Finally, the extracted electrons collide with the counterpropagating laser, which generates a QED cascade. Here, the processes are studied for various laser intensities, angle of incidence and point of incidence at the surface.
