A new study in Nature Photonics details the unique properties of the UCF-developed laser beam. The speed of a message traveling in these packets is no longer affected by traveling through different materials of different densities. University of Central Florida researchers have developed a new type of laser beam that […]

An artistic impression sharing a secret using structured light. Credit: Wits University Wits Researchers have demonstrated a new quantum approach for sharing a secret amongst many parties, setting a new record for the highest dimensions and parties to date. Researchers at the University of the Witwatersrand in Johannesburg, South Africa, […]

ANIMATION Ultrashort laser pulses induce unusual sound waves via a structural instability in a material. RIKEN physicists have initiated unusual sound waves in a flake using ultrashort pulses of laser light and then created videos of their movement using electron microscopy. This advance should help engineers to achieve higher precision […]
