Ponderomotive scaling in the radiative damping regime
Abstract
The ponderomotive force for super intense laser matter interactions has been derived by taking into account the higher order terms of radiative damping. The ion acceleration via collisionless shock, generated by both the ponderomotive pressure of the intense laser pulse during the interaction and the electron acceleration, becomes less efficient due to the radiative damping. A new ponderomotive scaling has been derived by applying the force with the radiation reaction to the super intense laser regime, and it is benchmarked by a particle-in-cell simulation with the radiative damping terms included in equations of motion. We find good agreement between theoretical and simulation results in terms of shock velocity and accelerated ion energy.
