Phase-cycling schemes for pump-probe beam geometry two-dimensional electronic spectroscopy

Experimental demonstrations and detailed theoretical explanations are provided for a thorough understanding of the various phase-cycling schemes in an optical pulse shaper assisted two-dimensional electronic spectroscopy (2DES) in a pump-probe beam geometry. We show that two and three-step phase-cycling schemes can be employed to retrieve both rephasing and nonrephasing 2D spectra. The studies were performed on the Q(y) transition of chlorophyll a.
