In this paper, the electromagnetic solitary wave due to the interaction of laser pulse and plasma media was studied by using a system of the nonlinear electron hydrodynamics and Maxwell’s equations. The Tsallis distribution function is assumed for the electron particles. By implementing the multiple scales technique, the nonlinear Schrodinger equation govern on the vector potential was derived. Analytically, the effects of nonextensive and nonthermal parameters on the condition of the modulation instability and existence of the types of envelope modes (bright and dark), were discussed in detail. Finally, the regions of the modulation stability and instability were studied numerically by plotting some figures.
