to material parameters such as occupation numbers, carrier density, and molecular

orientation. In this chapter we discuss a selection of fs experimental techniques,

many of them originally developed for ps and ns spectroscopy.

The obvious temporal limitation of the pump–probe technique is the duration

of the pump and probe. The medium preparation should be completed before

the material can be probed. If the physics of the interaction is well understood,

a theoretical modeling (deconvolution) can provide some interpretation of data

corresponding to partial temporal overlap of pump and probe.

A compromise often must be sought between spectral and temporal resolution.

Either the probe or the pump pulse has to select a specific
