Abstract: (1548 Views)
In this paper, the phenomenon of self-focusing of Gaussian laser beam with right and left circular polarization propagating in a magnetized plasma has been investigated in a weakly relativistic regime. For this purpose, using the Maxwell equations and the plasma-governing equations, a nonlinear equation describing changes in the amplitude of the beam is obtained. Then, the effect of external magnetic field on the self-focusing of the beam with the right and left circular polarization is investigated. It is shown that applying a longitudinal magnetic field in the plasma which causes the growth in the self-focusing of the right-circularly polarized beam and increase in the divergence of the left-circularly polarized beam is observed. Also, the role of the beam intensity and frequency on the self-focusing of the Gaussian beam is shown.
