Coherent multidimensional spectroscopy is a powerful tool to study electronic couplings and coherences of molecular systems. We present a novel all-collinear setup to perform pulse-shaper-assisted two-dimensional electronic spectroscopy with fluorescence detection. The variation of the interpulse delays and their relative phases (phase cycling) is performed shot-to-shot with a pulse shaper (Dazzler, Fastlite) with 1 kHz rate, enabling a rapid data acquisition. We show data of a 4-pulse excitation of cresyl violet in the liquid phase and compare it with data acquired in the non-collinear BOXCAR geometry. With the applied acquisition scheme, rephasing and non-rephasing contributions can be extracted from one single measurement session via phase cycling.
