SELF-FOCUSING OF ASYMMETRIC FINITE AIRY–GAUSSIAN LASER BEAMS IN PLASMA WITH EXPONENTIAL DENSITY RAMP
Abstract
Based on paraxial and Wentzel-Kramers-Brillouin (WKB) approximations, we investigated density transition-based self-focusing of asymmetric finite Airy–Gaussian (AiG) beams in plasma. The relativistic nonlinearity in the dielectric constant of plasma is considered. The electric field distribution of asymmetric finite AiG beams is expressed in terms of beam-width parameters f1 and f2 with respective modulation parameters a and b in transverse dimensions of the beam. The coupled differential equations governing the behavior of f1 and f2 with dimensionless propagation distance ξ are established from the parabolic equation approach. The effect of the exponential density ramp profile on the self-focusing of asymmetric finite AiG beams is presented. The sensitiveness of asymmetry in a and b parameters of finite AiG beam and exponential density ramp of plasma is specifically highlighted.
