Description
We propose and demonstrate experimentally an ultrafast chirality spectroscopy technique based on non-collinear harmonic generation, which relies only on electric-dipole interactions. The scheme is based on symmetry breaking, i.e. the chiral signal resides in harmonics that are forbidden when the medium is achiral/racemic, leading to a background-free signal. Moreover, by controlling the pump’s symmetry properties the technique also yields a huge enantio-sensitive response – we experimentally measure 163% R/S selectivity.
