Abstract
Spectral interferometry is used to study picosecond acoustic pulse propagation in a submicron titanium film heated by femtosecond laser pulse through a glass substrate. The melting depth was estimated from a moment of spall pulse arrival, formed due to cavitation in melt during tensile stress relaxation.
