In this theoretical work, we develop a comperehensive scheme for the generation of THz-radiation with the help of two fs laser pulses under the action of applied d.c. electric field and transeversly applied magnetic field on a collisional plasma. The Action of Filamentation between fs pulses on a collisional plasma plays an important role under the action of applied d.c. electric field and transeverse magnetic field, resulting in non Linear coupling . In this way, non linear electro magnetic force comes in to action known as ponderomotive forece and causes non Linear transverse oscillatory current that produces excitations at resonance to generate THz-radiation. The amplitude of THz-radiation can be enhanced by varying magnitude of magnetic field and electric field.
