A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

Physicists propose a novel way to create photoconductive circuits, where the circuit is directly patterned onto a glass surface with femtosecond laser light. The new technology may one day be useful ...

Cancer diagnoses traditionally require invasive or labor-intensive procedures such as tissue biopsies. Researchers at the Ludwig-Maximilians-Universität München (LMU) have now reported on a method ...

Laser engraving uses a powerful beam of light to create detailed designs on various materials. The laser works by vaporizing the surface layer, leaving behind precise and lasting marks or etchings.
