Abstract
This study aims to investigate the impact of helical wiggler magnetic field on the terahertz (THz) radiation amplification generated by beating of two super-Gaussian laser beams in a collisional and rippled density plasma. We derive the equations governing the THz radiation and show that the wiggler magnetic field has significant effects on enhancing the THz radiation field, power, and efficiency. For instance, the wiggler magnetic field can enhance the THz radiation electric field more than one order of magnitude, which can be very important in the generation of THz radiation. Also, under the same conditions, we compare the effects of wiggler magnetic field and conventional (uniform) magnetic field, used vastly in literature, and show that the THz radiation field generated in the presence of wiggler magnetic field is several times greater than the THz radiation field generated in the presence of conventional magnetic field.
