Two-dimensional photon-echo electronic spectroscopy is an excellent tool for the study of the
optical properties of molecules and excitonically-coupled systems. The short excitation pulses
(tens of fs), driving coherently the vibrational modes in the ground and excited states of a
molecule, have been used in such measurements to maximize an excitation bandwidth and to
provide a large spectral window for probing spectral evolution of quantum systems. I will
briefly introduce this new spectroscopic technique and fundamental issues related to
formation of the two-dimensional spectra, and give an excursus into new developments based
on implementation of diffractive optic for the multi-beam interferometers .
Further, recent results obtained using new coherent control strategies for multidimensional
spectroscopies will be discussed in terms of probing level-dependent dephasing and quantum
decoherence, as well as experimental evidence for controlling quantum decoherence in
complex systems . These new developments have attained what can be considered the
optical equivalent of NMR.
