Femtosecond Optical Spectroscopy from the Point
of View of a Theoretician
Abstract
Nonlinear femtosecond optical spectroscopy comprises a family of techniques such as
fluorescence up-conversion, pump-probe, transient grating, photon echo, coherent anti-Stokes-
Raman scattering, etc. These techniques differ in the number, ordering, and phase-matching
directions of the pulses involved and in the specific information they deliver on the material
system under study.
I will present my personal perspective on the development of nonlinear femtosecond
spectroscopy from the point of view of a theoretician. Focusing on transient absorption pump-
probe spectroscopy and three-pulse photon-echo two-dimensional (2D) spectroscopy, I will
clarify the information content of these techniques and demonstrate how the dynamic of the
material system under study can be uncovered from measured time- and frequency resolved
signals.
