Abstract
Transient grating techniques are shown to be a very well adaptetd method to follow the response of a material to short laser excitation pulses. Besides its enhanced sensitivity this technique is suited for the study of processes requiring a spatially modulated excitation of the medium. The choise of experimental conditions will select the response mechanismes and generate differente types of gratings. Each type wille be illustrated by an example.
