A team of physicists has just modeled an astonishing quantum phenomenon where ultra-powerful lasers generate light from vacuum. This work could soon be experimentally validated thanks to a new ...

All objects emit heat in the form of infrared light. This effect is strongest in dry, clear air, especially on cloudless nights. As a result, objects can become colder than the surrounding air. For ...

Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using ...

A research team under the direction of Prof. Dr Felix Deschler at Heidelberg University’s Institute for Physical Chemistry has developed a semiconductor that efficiently generates light and ...

Researchers propose an unconventional way to generate light made from entangled photons. In the graphic above, photons meet the electrons of a helium atom, which then emits two entangled photons.

A new kind of laser uses tiny moving particles to produce beams of light. The laser is more programmable than standard lasers and the approach could be used to create visual displays that are sharp ...
