Understanding random lasing is a formidable theoretical challenge. Unlike conventional lasers, random lasers have no resonator to trap light, they are highly multimode with potentially strong modal ...

Physicists in France are the first to create a random laser in a cloud of cold atoms under laboratory conditions. The effect was first seen decades ago in stellar clouds and the team believes that its ...

When we first heard the term “random laser,” we did a double-take. After all, most ordinary sources of light are random. One defining characteristic of a traditional laser is that it emits coherent ...

Researchers have demonstrated for the first time that a newly emerging technique known as random Raman lasing emission can produce a bright, speckle-free, strobe light source with potential ...
