Influence of the Faraday effect on stimulated backward scattering of light

It is shown that opposite rotation of the directions of polarization of the pump and scattered waves in an external magnetic field may reduce the intensity gain g (cm^–1). The greatest change (by a factor of two compared with the initial value of the gain g₀) should be observed when the magnetic rotation Ф (rad/cm) exceeds g₀/8 in the case of a linearly polarized pump wave.
