Abstrakt: Theoretical investigation on self-focusing of q -Gaussian laser beam propagating through underdense plasma has been presented. The optical nonlinearity of plasma has been modeled by the relativistic mass nonlinearity of plasma electrons in the field of laser beam. Using variational theory approach, semi-analytical solutions of the wave equations for the fields of main beam and that of ripple have been obtained. Emphasis has been put on the evolutions of the intensities of main beam and that of ripple. [ABSTRACT FROM AUTHOR]
