Abstract

The stimulated Raman backscattering of an intense electromagnetic wave propagating in the extraordinary mode along a uniform, static magnetic field is considered. The dispersion relation for a homogeneous magnetized plasma in the presence of the circularly polarized pump wave is developed in the cold-plasma approximation with the pump frequency above the plasma frequency. Formulas are derived for the threshold nu 0T of the parametric instability and for the groWth rate gamma of the backscattered extraordinary wave and Langmuir wave. The effects of the static magnetic field parallel to the direction of propagation on nu 0T and gamma are studied numerically.
