"In this work the influence of radiation reaction on the interaction of an electron bunch with a strong laser field is studied including nonlinear and quantum effects.\r\nThis venture is motivated by two technological developments: On the one hand, the tremendous increase in available laser intensities and, on the other hand, the\r\nsignificant advancements in electron acceleration technology. Considering a regime where radiation reaction effects are caused by the incoherent emission of several\r\nphotons, a kinetic approach is developed to describe the dynamics of electrons and photons via distribution functions. Whereas classical electrodynamics, employing\r\nthe Landau-Lifshitz equation, predicts a narrowing of the energy distribution of the electron beam, the analysis in this work reveals the opposite effect in case that quantum\r\neffects become significant. The spreading of the electrons' energy distribution is shown to be caused by the intrinsic stochastic nature of photon emission. In order to explain quantitatively the discrepancy between classical and quantum radiation reaction, the final electron distribution as computed in our quantum treatment is demonstrated to depend on the laser's envelope shape and its duration at a given total laser fluence. On the contrary, the classical analysis does not exhibit such a dependency. Finally, the kinetic approach is extended to allow for the inclusion of\r\npair creation by photons emitted during the scattering. This facilitates a conclusive investigation of the nonlinear coupled dynamics of all particles involved in the\r\ninteraction, i.e., electrons in the initial bunch, photons and electron-positron pairs produced during the scattering."^^ .
