  A new scheme for enantiomer differentiation of chiral molecules using a pair
of linearly polarized intense ultrashort laser pulses with skewed mutual
polarization is presented. The technique relies on the fact that the
off-diagonal anisotropic contributions to the electric polarizability tensor
for two enantiomers have different signs. Exploiting this property, we are able
to excite a coherent unidirectional rotation of two enantiomers with a {\pi}
phase difference in the molecular electric dipole moment. The approach is
robust and suitable for relatively high temperatures of molecular samples,
making it applicable for selective chiral analysis of mixtures, and to chiral
molecules with low barriers between enantiomers. As an illustration, we present
nanosecond laser-driven dynamics of a tetratomic non-rigid chiral molecule with
short-lived chirality. The ultrafast time scale of the proposed technique is
well suited to study parity violation in molecular systems in short-lived
chiral states.
