Versatile setup for high-quality rephasing, non-rephasing, and double quantum 2D electronic spectroscopy

Two-dimensional electronic spectroscopy based on passive phase stabilization methods is now well known and widely employed worldwide. In the most recent fully non-collinear implementations, a great phase stability is often achieved at the expense of the independent control over the pulse timings, limiting the full potential of the technique. Here we propose several modifications in the experiment geometry, calibration procedures, and data acquisition and processing routines. The setup is easily tunable to record different phase-matching directions, such as rephasing, non-rephasing and double quantum signals, still maintaining high levels of phase control and phase stability. The performances of the proposed setup are exemplified by measures on the standard dye zinc phtalocyanine and porphyrin J-aggregates.
