Abstract

With the aid of large-scale three-dimensional quantum electrodynamics (QED)-particle-in-cell simulations, we describe a potential experimental configuration to measure collective effects that couple strong field QED to plasma kinetics and develop a simple analytic model that describes the absorption due to radiation emission. For two counter propagating lasers interacting with a foil at intensities exceeding 10(22) W cm(-2), a near-binary result occurs; when quantum effects are included, a foil that classically would effectively transmit the laser pulse becomes opaque. This is a dramatic change in plasma behavior, directly as a consequence of the coupling of radiation reaction and pair production to plasma dynamics.
