A generalized dispersion relation for Stimulated Raman Scattering driven by a partially coherent pump field is derived, revealing a growth rate dependence, with the coherence width $\\sigma$ of the radiation field, scaling with $1/\\sigma$ for backscattering (three-wave process), and with $1/\\sigma^{1/2}$ for direct forward scattering (four-wave process).
