The interaction of intense femto second laser pulses with overdense foil targets is investigated by particle‐in‐cell (PIC) simulations. Effects like electron acceleration and recirculation, ion sheath acceleration and the formation of an electrostatic shock are observed. Ions are accelerated at the shock front, leading to a second ion population emerging from the foil backside. Amplification of laser pulse harmonics, as well as the generation of low frequency waves are observed.
