An improved laser-distillation method for complete enantio-conversion of chiral mixtures

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