title: Spatiotemporal evolution of high-power relativistic laser pulses in electron-positron-ion plasmas.
abstract: The spatiotemporal pulse dynamics of a high-power relativistic laser pulse interacting with an electron-positron-ion plasmas is investigated theoretically and numerically. The occurrence of pulse compression is studied. The dependence of the mechanism on the concentration of the background ions in electron positron plasma is emphasized.
