Starting from the generalized Zakharov equations, considering the pump wave as a pair of oppositely propagating Langmuir waves with different amplitudes, and the excitation of electromagnetic and induced Langmuir waves, we obtain a general dispersion relation for the coupled waves. We numerically solve the general dispersion relation using the pump wave amplitude and plasma parameters observed in the interplanetary medium.enCopyright (c) 2003 Progress of Theoretical PhysicsJournal article002003094610.1143/PTPS.151.2260001861216000332-s2.0-034759226258507Chian, A.
