Title

Stimulated Raman scattering of beat wave of two counter-propagating right circularly polarized lasers in an axially magnetized plasma

Pages

  30-36

Abstract

 The stimulated Raman scattering caused by beating of two counter-propagating lasers in Magnetized plasma has been investigated. The input waves have a right circular polarization and the plasma is embedded in a uniform axial external magnetic field. Also, the difference in frequency of the input waves is more than twice that of the plasma frequency. Pandromotive force generated by the Beat wave excites a plasma wave and scatter the Beat wave in the plasma. The nonlinear current density due to the coupling of the plasma wave and the Beat wave causes the amplitude of these waves to increase. By using the equation of motion of electrons as well as the wave equation, the dispersion relation of the scattered wave and the Growth rate of instability have been obtained. It shows that the presence of the magnetic field increases the maximum Growth rate. Also, the growth increases by increasing the external magnetic field, so that, the instability is exacerbated at the cutoff frequency. Also, the greater the difference in the frequency of the two waves of pumps, the more the Growth rate.
