Synopsis

A new mechanism of generating electromagnetic radiation from high density magnetized plasma has been studied theoretically and experimentally. In this radiation scheme, a large amplitude plasma wakefield is generated by an intense laser pulse or a relativistic electron bunch in the presence of a modest perpendicular dc magnetic field. The initial motion of plasma electrons due to the laser ponderomotive force make them rotate around the magnetic field lines and generate the electromagnetic (EM) part in the wake with a nonzero group velocity. The magnetized wakefield propagates through the plasma and couples to vacuum at the plasma-vacuum boundary.
