By shining a focused laser beam onto a sample of material, a team at the Paul Scherrer Institute (PSI) and ETH Zürich showed ...

When a semiconductor material called black phosphorus is hit with intense laser light, the behaviour of its electrons is found to change. The discovery opens a route to time-dependent engineering of ...

UPTON, NY—Lasers are intense beams of colored light. Depending on their color and other properties, they can scan your groceries, cut through metal, eradicate tumors, and even trigger nuclear fusion.

For the first time, physicists have generated and observed stable bright matter-wave solitons with attractive interactions ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

Just as flicking on a flashlight reveals the objects in a dark room, pointing a laser at a cloud of gas can reveal a lot about the atoms and molecules floating in it. Zhili Zhang, a B. Ray Thompson ...

Scientists show that it is possible to make a femtosecond laser that fits in the palm of one's hand using a glass substrate. Is it possible to make a femtosecond laser entirely out of glass? That's ...
