Stimulated Brillouin and Raman scattering of laser radiation at the upper hybrid frequency in a hot, collisionless, magnetized plasma
In this paper we have made a theoretical investigation of the stimulated Brillouin and Raman backscattering of laser radiation at the upper hybrid frequency in a laser-produced plasma, taking into account the effects of a spatially uniform self-generated magnetic field of the order of a few megagauss. The Vlasov equation has been employed to obtain the nonlinear electron density perturbation due to the low-frequency short-wavelength electrostatic mode and the current density due to the high-frequency, unmagnetized, scattered laser radiation in the plasma. This kinetic treatment is valid for plasmas produced by both CO/sub 2/ and Nd-glass lasers and short-wavelength perturbations. It is noticed that the growth rates for both Brillouin and Raman backscattering increase with the self-generated magnetic field.
