Enantioselective chiral orientation induced by a combination of a long and a short laser pulse

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