The driven coupled mode equations are derived for a two fluid, unequal temperature (T/sub e/ much greater than T/sub i/) plasma in the one-dimensional, electrostatic model and applied to the coupling of electron plasma waves. It is assumed that the electron to ion mass ratio identical with m/sub e/M/sub i// much less than 1 and eta$sup 2$/sub ko/k lambda/sub De/ less than 1 where eta$sup 2$/ sub ko/ is the pump wave's power normalized to the plasma thermal energy, k the mode wave number and lambda/sub De/ the electron Debye length. Terms up to quadratic in pump power are retained. The equations describe the linear plasma modes oscillating at the wave number k and at $omega$/sub ek/, the Bohn Gross frequency, and at $Omega$/sub k/, the ion acoustic frequency, subject to the damping rates $nu$/sub ek/ and $nu$/sub ik/ for electrons and ions and their interactions due to intense high frequency waves E/sub k//sup l/. n/sub o/ is the background density, n/sub ik/ the fluctuating ion density, $omega$/sub pe/ the plasma frequency.
