At IPPL, systems have been developed for the generation and detection of high-frequency acoustic waves through the interaction of short-duration laser pulses with material surfaces, with applications in nanotechnology for the investigation of the elastomechanical properties of simple, composite materials and metamaterials. Moreover, specialized and innovative methods are developed, based on the generation of acoustic waves using piezoelectric transducers and/or pulsed laser sources to achieve dynamic modification of the crystal structure.
