Ultrafast Acoustic Pulses Induced by Femtosecond Pulses and the Dynamics of Materials

Ultrafast acoustic pulses induced by a femtosecond laser can be considered as pure mechanical pressure pulses, excluding energy transitions of electrons caused by photons and thermal energy. This special issue discusses methods for controlling the dynamics of magnetic materials using ultrafast acoustic pulses and outlines the latest research trends. Additionally, it presents potential applications of acoustic pulses not only in magnetic materials but also in phase-transition materials.
