The interaction of solids with high-intensity ultra-short laser pulses has enabled major technological breakthroughs over the past half-century. On the one hand, laser ablation of solids offers ...

The reaction kinetics of energetic materials is a key factor in determining the detonation characteristics and safety. The complexity of the reaction process and the lack of experimental means remain ...

This optical micrograph shows an array of microscopic metamaterial samples on a reflective substrate. Laser pulses have been digitally added, depicting pump (red) and probe (green) pulses diagnosing a ...

The ultrashort pump laser pulse interacts with a 10 nm-thick diamond-like carbon foil (DLC). The interaction region is illuminated with a probe laser pulse with a large optical spectrum, whose various ...

A chip-sized structure made of silicon nanopillars floated off a surface inside a Cornell University lab, pushed upward by nothing but focused laser light. The tiny device, smaller than a grain of ...

A new technique offers a safe, reliable, and high-throughput way to dynamically characterize microscale metamaterials. The method could speed up the development of acoustic lenses, impact-resistant ...

With the help of computer simulations, engineers can play with any combination of microstructures to see how certain materials can transform, for instance, into sound-focusing acoustic lenses or ...
