Collinear two-dimensional spectroscopy via fluorescence detection with rapid phase cycling — •Simon Draeger1, Sebastian Röding1, Andreas Steinbacher1, Patrick Nürnberger1,2, and Tobias Brixner11Institut für Physikalische und Theoretische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg — 2Physikalische Chemie II, Ruhr-Universität Bochum, Universitätsstraße 150, 44780 Bochum

We present a novel all-collinear setup to perform pulse-shaper-assisted two-dimensional electronic spectroscopy with fluorescence detection. The acousto-optical pulse shaper (Dazzler, Fastlite) allows the variation of the interpulse delays and their relative phases with 1 kHz rate, enabling a rapid scan and shot-to-shot phase cycling. For a four-pulse sequence with variable delay times τ, T and t, the application of phase cycling allows to obtain different nonlinear contributions (e.g. rephasing and non-rephasing photon echo) in one single measurement process. Common laser dyes are used as benchmark molecules to evaluate the setup.
