Ultra-broadband two-dimensional spectroscopy from the visible to the UV.
Borrego-Varillas R., Oriana A., Ganzer L., Manzoni C., Cerullo G.
2D electronic spectroscopy (2DES) is the "ultimate" time-resolved optical experiment, since it provides the maximum amount of information within third-order nonlinear spectroscopy. By spreading the information content of the nonlinear signal on two frequency axes, 2DES allows to measure homogeneous linewidths, spectral diffusion, couplings and energy transfer between transitions. This talk will present a state-of-the art 2DES system in the visible and discuss the prospects of extending the technique to the UV range, for the study of biomolecules such as DNA and proteins.
