Terahertz radiation generation in magnetized plasma under relativistic effect

Abstract

We have carried out analytical calculations for the emission of Terahertz (THz) radiation in the magnetized and rippled density plasma by beating of two high intensity cosh-Gaussian laser beams, which are capable of creating a relativistic effect in electrons' motion. We find the expression for the THz field achieved during the relativistic laser plasma interaction and study the effect of density of ripples, laser beam width, and magnetic field on the THz field. The role of skewness parameters of the lasers is also discussed in detail for efficient THz radiation.
