In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric ...

Photonic-crystal surface-emitting laser (PCSEL) is a promising technology that can completely revolutionize what lasers can achieve. Such a system can produce highly directional, bright beams with ...

A 3D printer that uses lasers to build up an object in any order, rather than layer by layer, could produce more advanced designs than is currently possible. Existing 3D printers work by depositing ...
