  Enantioselective orientation of chiral molecules excited by a shaped
picosecond laser pulse and a delayed femtosecond pulse is considered. Using
quantum mechanical simulations, we demonstrate a strong field-free
enantioselective orientation along the laser propagation direction. In
addition, we use a classical model to reproduce the enantioselective
orientation. Moreover, the analysis of the corresponding classical system
allows understanding the qualitative features of the induced enantioselective
orientation. The strong enantioselective orientation may be used for the
separation of chiral enantiomers using inhomogeneous electrostatic fields.
