摘      要：The propagation of quadruple Gaussian laser beam in a plasma characterized by axial inhomogeneity and nonlinearity due to ponderomotive force in the paraxial ray approximation is *** appropriate expression for the nonlinear dielectric constant has been developed in the presence of external magnetic field,with linear absorption and due to saturation effects for arbitrary large *** effects of different types of plasma axial inhomogeneities on self-focusing of laser beam have been studied with the typical laser and plasma ***-focusing of quadruple Gaussian laser beam in the presence of externally applied magnetic field and saturating parameter is found significantly improved in the case of extraordinary *** results reveal that initially converging beam shows oscillatory convergence whereas initially diverging beam shows oscillatory *** beam is more focussed at lower intensity in both cases *** and ordinary mode.
