Abstract
Radiation energy losses of electrons in ultra-intense laser fields constitute a process of major importance when considering laser-matter interaction at intensities of the order of and above 1022 W/cm2. Radiation losses can strongly modify the electron (and ion) dynamics, and are associated with intense and directional emission of high energy photons. Accounting for such effects is therefore necessary for modeling of, electron and ion acceleration and creation of secondary photon on the forthcoming ultra-high power laser facilities. To account for radiation losses in the particle-in-cell code PICLS, we have introduced the radiation friction force using a renormalized Lorentz-Abraham-Dirac model.10 Here, we present a study of the effect of radiation friction on the electron and photon energy distribution in a semi-infinite and overdense plasma. A possibillity to create a collisonless shock using an ultra intense laser field, in the context of laboratory astrophysics is discussed. The influence of the radiation reaction on the plasma dynamics is demonstrated.
