Self-consistent theory of radiation friction losses in ultraintense laser-plasma interaction — •Tatyana Liseykina1,2, Sergey Popruzhenko3,4, and Andrea Macchi5,61Institut für Physik, Universität Rostock, Germany — 2Institute of Computational Technologies, SD RAS, Novosibirsk, Russia — 3Max-Planck-Institut für Physik komplexer Systeme, Dresden — 4National Research Nuclear University, Moscow Engineering Physics Institute, Russia — 5CNR, National Institute of Optics, Pisa, Italy — 6Department of Physics, University of Pisa, Italy

In the interaction of laser pulses of extreme intensity with high-density, thick plasma targets, collective effects lead to very strong radiation friction losses. We present a classical model for this regime, based on the Zel'dovich solution [1] for the electron motion in the presence of a steady electric field. This improves our previous modeling [2] by making the radiation losses self-consistent with the electron dynamics. The model predicts that in the present context the classical regime of radiation friction is applicable up to intensities still beyond the capabilities of next generation facilities.
