In this paper, the interaction between two Lambda-type three-level atoms and a single-mode field is investigated in the presence of detuning parameters and dissipation. Assuming that the two atoms are initially prepared in their excited states and the field is in a coherent state, the state vector of the total system is obtained analytically under resonance conditions in the absence of dissipation, and numerically under off-resonant conditions in the presence of dissipation. The entanglement between the atoms and the field is quantified using the linear entropy, while the entanglement between the two atoms is evaluated by means of the negativity measure. The numerical results show that the behavior of the entanglement measures strongly depends on the system parameters, and that both the maximum value and the persistence of entanglement can be controlled by adjusting the resonance conditions and the strength of dissipation.
