Abstract  In a partially ionized plasma the presence of bound electrons can significantly alter the laser plasma parametric instabilities. In this paper the nonlinear dispersion relation in intense laser partially ionized plasma is analysed. The growth rate of the forward stimulated Raman scattering is significantly enhanced by the presence of bound electrons; on the other hand the backward stimulated Raman scattering is unaffected.
Keywords:  intense laser partially ionized plasma      growth rate      forward stimulated Raman scattering
