Abstract: We demonstrate strong laser-field-free orientation of ground-state-selected carbonyl sulphide molecules via coherentsuperposition of its two lowest rotational states. The states were coupled by the combined action of a 485-ps-longnon-resonant laser pulse and a weak static electric field. The o bserved wave packet motion exhibits strong transientmolecular orientation after the control laser pulse has been switched off. The experimentally attained degree of orientation〈cos θ〉 ≈ 0.6 corresponds to the theoretical maximum for mixing of the two states. Simulations show that switchingoff the static field would provide the same orientation complete ly field free.
