The high energy radiation that carry the orbit angular momentum has become an extremely important tool to investigate the angular momentum related physics in microworld. But the generation and ...

Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum of laser beams. Nature Photonics today published research by a team from South ...

Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly ...
