The paper presents an investigation of growth dynamics of spike in a collisional magneto plasma in the presence of externally applied magnetic field. We have set up and solved the non‐linear differential equations for growth and width of the laser spikes. We have considered the mechanism of nonuniform heating of carriers along the wavefront which is important in collisional plasmas. The effect of...
Summary form only given as follows. In the present paper we have investigated the growth of a radially symmetrical ripple, superimposed on a Gaussian laser beam and its effect on ion-acoustic wave excitation by considering the interaction of a weak ion-acoustic wave and the rippled Gaussian laser beam in relativistic plasma. We have set up and solved ordinary differential equations for the beam width...
