New class of laser beam doesn't follow normal laws of refraction
University of Central Florida researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels.
The findings, which were published recently in Nature Photonics, could have huge implications for optical communication and laser technologies.
"This new class of laser beams has unique properties that are not shared by common laser beams," says Ayman Abouraddy, a professor in UCF's College of Optics and Photonics and the study's principal investigator.
The beams, known as spacetime wave packets, follow different rules when they refract, that is when they pass through different materials. Normally, light slows down when it travels into a denser material.
