Abstract

Abstract: Laser-assisted enantio-conversion is an ambitious issue related to chiral molecules in atomic, molecular, and optical physics. The theoretical laser-distillation method was proposed to realize enantio-conversion based on a four-level double-Δ model of two degenerated chiral ground states and two achiral excited states. Here, we re-investigate and improve the laser-distillation method so that a chiral mixture can be converted to an enantiopure sample of the desired chirality, i.e. complete enantio-conversion, which has not been discussed in previous theoretical works on the laser-distillation method. Since the undesired chirality may be inefficient, or even cause serious side effects in pharmacology, our work provides an important improvement to the original theoretical works on laser-assisted enantio-conversion.
