A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

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

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

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 single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...

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 ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...
