Researchers at Rensselaer Polytechnic Institute have created a supersolid, a state of matter that simultaneously behaves like ...

The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers from Stockholm University, the Nordic Institute for ...

A compact ultraviolet-B (UV-B) semiconductor laser diode emitting at 318 nm under continuous-wave operation at room-temperature. The device demonstrates stable UV-B lasing on a low-cost sapphire ...

Although the detailed physics of what goes on inside a laser is typically complex, all conventional lasers share a common basic operational principle: a process known as the stimulated emission of ...
