Abstract

When an intense right-hand circularly polarized laser pulse propagates through a highly magnetized (in the direction of laser propagation) foil into the vacuum region between this foil and an unmagnetized foil, it can be multiply reflected and thus quasitrapped between the two foils until its energy is depleted. During the multiple reflections at the magnetized foil, foil electrons are accelerated by the laser light. Electrons that have gained sufficient energy can escape and appear as periodic energetic electron bunches at a time interval determined precisely by the trapping time or the distance between the two foils.
