I will describe new, extremely efficient approaches to chiral discrimination, which take advantage of ultrafast electronic response [1,2]. In particular, I will describe the new concept of synthetic chiral light [3], which can be used to trigger bright nonlinear optical response in the molecule of a desired handedness while keeping its mirror twin dark in the same frequency range. The simplicity of generating synthetic chiral light in a laboratory opens a broad field of shaping and controlling chiral matter with light. I will also outline the potential for chiral discrimination enabled by using few-cycle, carrier-phase stable laser pulses.
