摘要：

We studied the dynamics of entanglement in ultra-cold heteronuclear diatomic rovibrational molecules driven by an infrared laser field. Environment-induced spontaneous emission is considered. Numerical results show that the resonant external field and damping processes can bring into equilibrium and the disentanglement can be suppressed evidently. Appropriate intensity of far detuned pulses can also suppress disentanglement and produce some entanglement if there is initially separable state, but damping processes and interaction via polarizability dominate the disentanglement, leading to the vanishing of entanglement after a long time.
