Coherent multidimensional optical spectroscopy is an emerging technique for resolving
structure and ultrafast dynamics of molecules, proteins, semiconductors, and other materials.
A current challenge is the quality of kinetics that are examined as a function of waiting time.
Inspired by noise-suppression methods of transient absorption, here we incorporate shot-by-
shot acquisitions and balanced detection into coherent multidimensional optical
spectroscopy. We demonstrate that implementing noise-suppression methods in two …
