Summary:O4; Entanglement is used to measure correlation between separated subsystems. yon Neumann entropy is used to study evolutions of entanglement of atoms in processes of interaction between atoms with the field prepared in coherent state. The effects of field intensity and detuning on entanglement are investigated. It is shown that the entanglement exhibited oscillations in its evolutions, their amplitudes and mean values decrease with increasing field intensity. Oscillation frequencies increase with detuning, but the maximum values are almost independent of detuning.
