The growth rate for the Raman scattering instability has been found for the case when the plasma flow has a component perpendicular to the wave vector of the pump. Such a configuration allows the pump and the scattered waves to be linearly converted into corresponding longitudinal waves. The linear conversion has a resonant character that results in an enhancement of the growth rate of the parametric process.
