Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics ...

In a potential step toward sending small spacecraft to the stars, researchers have developed an ultra-thin, ultra-reflective ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

You can’t make a quality laser from silicon ... But the necessary light-emitting materials, compound semiconductors made of elements pulled from the third and fifth column of the periodic ...

And with the correct choice of laser wavelength, the light can destroy one type of material, while leaving others intact. Furthermore, laser power can be used in a blunt way, such as welding parts ...

A small international team of nanotechnologists, engineers and physicists has developed a way to force laser light into becoming a supersolid. Their paper is published in the journal Nature.
