By means of numerical calculations,the dipole squeezing of a Λ-type three-level atom interacting with two-mode entangled coherent states is investigated.The influences of the degree of entanglement of two-mode entangled coherent optics field and mean photon numbers of two-mode optics field on dipole squeezing of a Λ-type three-level atom are discussed.The results show that squeezing effect weakens with increase of degree of entanglement of two-mode entangled coherent optics field and with increasing of mean photon numbers of two-mode entangled coherent optics field.
