Abstract:

Electron acceleration by Frequency chirped radially polarized (RP) axicon Gaussian laser pulse in vacuum in the presence of wiggler magnetic field is studied. A strong longitudinal electric field is produced by axicon Gaussian laser pulse which is crucial and responsible for direct electron acceleration in vacuum. Linear frequency chirp enhances the interaction time between laser and electron however, the applied wiggler magnetic field helps in improving the strength of ponderomotive force so that the electron traversing in the accelerating phase up to longer distances. It is observed that an electron with initial energy of few MeV accelerates up to GeV energy with optimized laser and magnetic field parameters. A significant enhancement in the electron energy gain is seen in the presence of wiggler magnetic field.
