Time Resolved Spectroscopy

Abstract

In this course we will introduce the fundamentals of time resolved spectroscopy, discussing briefly pulse generation techniques and ultrashort optical pulses properties, the light matter interaction relevant to ultrafast processes and the phenomena occurring following ultrafast excitation in molecules and solids. Finally, an outlook on new emerging techniques will be presented
