We find the components of the terahertz radiation for the relativistic laser plasma interaction, i.e. beating of the two lasers of same amplitude and different frequency in under dense plasma. We plot the electric field profile of the emitted radiation under the effect of lasers index. By creating a dip in peak of the incident lasers’ fields, we can achieve multifocal terahertz radiation.}, number={2}, journal={Journal of Theoretical and Applied Physics}, publisher={OICC Press}, year={2023}, month={Nov.}, keywords={Relativistic effect, Rippled plasma, Coshyperbolic, Gaussian lasers, Laser index, Multifocal terahertz radiation} }
