    Excitation of Electron Plasma Wave by Self Focused Cosh-Gaussian Laser Beams in Collisionless Plasmas: Effect of Density Ramp

    Dynamics of the laser-driven electron plasma waves (EPWs) in plasmas with axial density ramp has been investigated theoretically. The effect of self-focusing of the laser beam on the power of laser-excited EPW...

    Stimulated Brillouin Scattering of Elliptical q-Gaussian Laser Beams in Plasmas with Axial Density Ramp: Effect of Self-Focusing

    Theoretical investigation on stimulated Brillouin scattering of intense q-Gaussian laser beams interacting with axially nonuniform plasmas has been presented. A ramp-shaped density profile has modelled the axi...
