Dynamic diagnosis of metamaterials through laser-induced vibrational signatures

A high-throughput, non-contact framework is described that uses the laser-induced vibrational signatures of metamaterials to non-destructively quantify their omnidirectional elastic information, dynamic linear properties, damping properties and defects.

High strain rate deformation of layered nanocomposites

Bullet-proof materials made of nanostructured composites outperform conventional materials, yet little is known of their nanoscale response to high-speed impact. Using laser-propelled microscopic projectiles, Lee et al.directly visualize this process in layered nanocomposites.

Ultrafast acousto-optic mode conversion in optically birefringent ferroelectrics

Electrically driven acousto-optic light modulators are limited to frequencies of a few hundred megahertz and are typically no smaller than a few micrometres. Here, the authors demonstrate gigahertz acousto-optic conversion of light polarization in a region of a few nanometres using pulsed laser stimulation of a ferroelectric.

Imaging grain microstructure in a model ceramic energy material with optically generated coherent acoustic phonons

Optically generated acoustic phonons have enabled depth resolved microstructure characterization. Here, the authors extend this method to obtain information on the orientation of individual crystallites by studying influence of probe beam polarization on detected signal amplitude.
