Stimulated Raman Scattering of High-Power Beam in Collisional Magnetoplasma
Abstract
The present problem investigates Stimulated Raman Scattering of high-power beam in Collisional magnetoplasma. The laser beam has two propagation modes viz. extraordinary and ordinary modes, while its transition along the direction of static magnetic fields. The carrier redistribution affected due to modification in static magnetic field. The carrier redistribution will take place due to non-uniform heating, which results in variation in density profile in a transverse direction to axis of main beam. This density profile further causes modification in all the three waves involved in the process viz. incident beam, electron plasma wave and scattered wave. Here, 2nd order ODE for beam waists of pump beam, EPW and back-scattered wave and also expression for reflectivity will be obtained and further their numerical simulations will be carried out in order to explore impact of change in laser and plasma parameters and also externally applied magnetic field on beam waists of various waves and on SRS back-reflectivity.
