Abstract:Studies the entanglement dynamic behavior of two two-level atoms initially in the coherent state during the spontaneous emission dissipative process and considers two cases with the external coherent laser field and without the external coherent laser field. It is shown that the entanglement between the two atoms depends on the initial state of the atoms, and the entanglement in the spontaneous emission dissipative process can be controlled by changing the relative phases and polarization amplitude. Meanwhile, obtains that the entanglement with the external coherent laser field is bigger than that without the external coherent laser field.
