ABSTRACT
Develops a theoretical model for self focusing of a Gaussian laser beam with step function temporal profile in a collisionless plasma in the paraxial ray approximation. Expression for modified electron density in the paraxial region as a function of space and time; Solution for the wave equation to obtain an equation for the beam width parameter.

    The growth of a ring ripple, riding on an intense Gaussian laser beam, through plasma has been studied. The amplitude ratio p of the ripple and the beam and the dimensionless width ρ1 of the ripple are chosen as significant coordinates. It is observed that the positive quadrant of the p,...

    The propagation of a Gaussian beam in underdense plasma with upward increasing density ramp is analyzed. In this work are shown that the spot size oscillations of laser beam increases and its amplitude shrinks with proper plasma density ramp. This causes the laser beam to become more focused and...

    Propagation of a Gaussian laser beam in a plasma is analyzed by including the nonlinearity associated with the relativistic mass and the ponderomotive force.

    In this paper, new expressions for spot size, radius of curvature, and Rayleigh length of a linearly and negatively chirped Gaussian beam are presented in paraxial approximation self-consistently.
