The two-mode Raman coupled model governed by the Milburn equation is studied by the dynamical algebraic method. With the help of an SU(2) dynamical algebraic structure, we find an exact solution of the Milburn equation for an effective two-mode Raman coupled Hamiltonian. The exact solution is then used to discuss the influence of intrinsic decoherence on nonclassical properties of the system, such as collapses and revivals of the atomic inversion, oscillations of the photon number distribution and squeezing of the radiation field.
