Abstract

A novel light source delivering few-cycle UV pulses is used to reveal an ultrafast modulation of the chiroptical properties of photoexcited chiral molecules, probed by time-resolved photoelectron circular dichroism. We report a periodic inversion of photoelectron emission direction in methyl-lactate on a timescale as short as 6fs.
