Résumé : A strategy for controlling molecular orientation dynamics for achieving both efficiency and duration of the postpulse orientation by using a train of half-cycles pulses (HCP), was discussed. The target states which fulfill both of these requirements were identified and characterized by the fact that they only involve a limited number of the lowest lying rotational levels and that they maximize the orientation efficiency within the corresponding restricted rotational spaces. By acting at appropriately chosen times these selected states were reached using a train of HCPs. The results show that the with the total number of HCPs and by chosing the pulse strengths, these target states can be achieved via good accuracy.
