Abstract

This research paper uses a non-paraxial approach to explore the intrinsic relationship between high energy electromagnetic l beams and their interactions with plasma. The thermal nonlinearity leads to a self-action generated lens effect, wherein high-power electromagnetic beams create a refractive index profile across their cross-section that mirrors their intensity profile, thus enabling the beam to self-focus within a nonlinear plasma medium. In this approach, many paraxial approximations are dropped. This study encompasses a comprehensive examination of laser-matter interactions across plasma. With a keen focus on the practical importance of the lowest order of nonlinear terms, this research sheds light on how an intense electromagnetic beam influences the effective refractive index and the dielectric constant of the medium it passes through, fundamentally altering the propagation characteristics of the beam and enabling novel applications in optical technologies. Through theoretical analysis and mathematical modelling, this paper contributes to a deeper understanding of the intricate dynamics at play in nonlinear optics and paves the way for future innovations in the field.
