Frequency comb-based multidimensional coherent spectroscopy

Abstract In this chapter a novel approach of multidimensional coherent spectroscopy is described. This approach uses multiple optical frequency combs and enables the measurement of comb resolution multidimensional coherent spectra in seconds. This chapter also shows how this new method can probe critical and fundamental processes in samples that have long dephasing times as well as can be used for practical applications such as chemical sensing and imaging.
