US researchers say they have built a laser system precise and powerful enough to control vast grids of atoms, a step they ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Ultraviolet light has always sat at the edge of human perception, powerful yet invisible, more associated with sterilizing ...

AUSTIN (KXAN) — Deep beneath the surface in a quiet corner of the basement of the Physics, Math and Astronomy building of the University of Texas at Austin, lasers blast electronics with simulated ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special technique to film laser light in real time, researchers observed how ...

For the first time, physicists have used lasers to deep-freeze antimatter. In a new experiment, an ultraviolet laser quelled the thermal jitters of antihydrogen atoms, chilling the antiatoms to just ...

High harmonics: a NIR pulse (red) is focussed, and high harmonics are generated in a gas jet that is placed before or behind the NIR focus. The generated XUV light (violet) has a size and divergence ...
