Abstract: The exact wave function is found in the work, the asymptotic solutions for system state vectors are obtained in the approximation of strong field for two-atom model with nondegenerate two-photon interaction. The reduced entropy dynamics is described for various initial atomic states and coherent field input, some conclusions about atom-field entanglement are made. We also show the possibility for the system being initially in the pure nonentangled state to revive into this state during the evolution process.
