The behavior of the dipole moment of a three-level atom interacting with cavity fields of arbitrary de-tunings is investigated. The time evolution and squeezing conditions of the components and correlation function of the dipole moment are calculated for three cases: One-mode field and Xi type-atom initially in the upper state, two-mode field and a Lambda-type atom initially in the upper state, and two-mode field and a Lambda-type atom initially in one of the lower states. A number of interesting features are found and discussed. Keywords: Three-level atom; Cavity fields; Nonresonant interaction; Atomic dipole moment; Correlation function; Squeezing effects.
