Abstract

A systematic numerical study on terahertz (THz) radiation by the interaction of laser with under-dense plasma with the inclusion of a variety of laser and plasma parameters is reported in the present communication. We have included the effect of the externally applied transverse magnetostatic field on the THz generation scheme reported by Mehta et al. (Laser Phys. Lett. 15(1):045403, 2019) in 2019. The externally applied magnetostatic field can be utilized to enhance the nonlinear coupling present between the plasma and electromagnetic waves as well as to control the various parameters of the emitted energy-efficient THz radiations. We demonstrate that the resonance attributed to nonlinear effects and broadening the emission spectra significantly can be tuned by varying the value of the externally applied magnetostatic field on the p-polarized laser pulses.
