fa Effect of frequency chirping on subcycle electron acceleration with two crossing plane-wave laser beams تخصصی Special پژوهشي Research In this paper vacuum electron acceleration by using two linearly polarized plane- wave laser beams, crossing at arbitary angles, has been studied. The effect of frequency chirping of laser beams on the electron acceleration has been investigated. The electron interacts with the laser beams at the crossing point of the two beams. With a proper chirp parameter, the electron could achieve higher energies by interaction on a half -cycle of the laser beams. Ferthermore, it is shown that with stronger laser beams and by using a preaccelerated electron, even more energetic electron at the end of the interaction length could be obtained. <br> In this paper vacuum electron acceleration by using two linearly polarized plane- wave laser beams, crossing at arbitary angles, has been studied.
