In this paper, we explore the population inversion and entanglement dynamics in a -qutrit interacting off-resonantly with a coherent cavity field through multi-quanta processes based on the intrinsic decoherence model. Exact solutions of the decoherence model are obtained when the initial cavity field state is considered in two different states, coherent state and even super-position coherent state. The dynamics of the population inversion and the qutrit–cavity negativity are investigated under the effects of the initial cavity states, and the detuning as well as the decoherence. The energy transfer and entanglement induced by the qutrit–cavityinteraction can be controlled by these effects. The qutrit–cavitydetuning and the coherent intensity and the nonclassicality of the initial cavity field play an important role in improving the generated entanglement dynamics.
