Barr, H C, Boyd, T J M and Lukyanov, A V (2000) Raman gain against a background of non-thermal ion fluctuations in a plasma. Journal of Plasma Physics. pp. 623-630. ISSN 1469-7807Full text available as:
A complex stimulated Raman scattering event against a background of non-thermal ion acoustic waves in an inhomogeneous plasma is described. We obtain analytic forms for the Raman gain due to a five-wave interaction consisting of conventional three-wave Raman scattering followed by the decay of the Raman Langmuir wave into a second Langmuir wave (or a second scattered light wave) and an ion acoustic wave. Very modest levels of ion waves produce a. significant effect on Raman convective gain. A combination of plasma inhomogeneity and suprathermal ion fluctuations may offer a means for the control of Raman gain.
