Abstract
Acoustic phonons are generated by the arrival of a femtosecond laser pulse to the surface of a material. By femtosecond pump-probe ellipsometry on thin films and bulk materials, we could discern between different types of transient phenomena including the ones due to the propagation of these photo-induced acoustic waves.
