This Laser Beam’s Behavior Runs Counter to Normal Laws of Refraction ORLANDO, Fla., Aug. 10, 2020 — A type of laser beam that does not follow the classical laws of refraction, discovered by a team at the University of Central Florida (UCF), could offer new opportunities for shaping the flow of light beams used for optical communications and laser applications. Normally, light slows down when it passes through a dense material. The new class of laser beams, called spacetime wave packets, can be arranged to not change speed at all, or even to speed up in denser materials. “As such,
