A general semi-classical model of wave packet excitation and evolution in strong single-color laser field has been set up. The simulating calculation demonstrated that a local mode vibration can be selectively excited by a strong resonant laser field, provided that the transition dipole moment from the ground state to the local mode vibrational state is much larger than those of the background (“bath”) states which are coupled with the local mode state.
