We use the Lewis-Riesenfeld invariant and superoperator methods to solve the svstern of the interaction of a two-level atom with two modes of a quantized field via multiphoton process. including any form of both intensity-de-pendent interaction and nonlinearity of the two-mode radiation field. The corresponding general atom-field wave func-tion and time evolution operator as well as the time-evolving expressions for both the atomic inversion and the photon numbers of two modes field are evaluated.
