Scanning technique and phase-stability in coherent 2D spectroscopy — Ulrike Selig, Florian Langhojer, Frank Dimler, Tatjana Löhrig, Christoph Schwarz, •Björn Gieseking, and Tobias Brixner — Institut für Physikalische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg

We have recently introduced an inherently phase-stable setup for coherent two-dimensional (2D) spectroscopy using only conventional optics [1]. In this contribution we discuss the underlying principle that ensures its stability, the exclusive manipulation of pulse pairs. We explain the technique of measuring the third-order optical response, the scanning procedure allowing for adequate variation of the time delays between the three pulses, and the analysis of the recorded data via Fourier evaluation.
