Laser synthesis of chiral molecules in isotropic racemic media

The problem of directional laser synthesis of enantiomers in an isotropic racemic mixture of chiral molecules is analyzed taking into account rotational degrees of freedom of molecules. It is shown that the chirality of the polarization structure of a laser field is the most general necessary condition for the laser distillation of an isotropic non-racemic mixture of chiral molecules with the isotropic distribution over the Eulerian angles. In the approximation of the electric-dipole interaction, the required field configuration can be provided due to noncoplanarity of the polarization vectors of laser-pump components. A relevant experimental scheme is proposed and calculated for the transformation of an isotropic racemic mixture with the help of a three-component pulsed laser field. It is shown that the possibility of the laser control of chirality in an isotropic medium corresponds to nonzero information on coupling between the input and output in the laser field-chiral molecular state information channel.
