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

Scientists have demonstrated that light alone can reversibly control magnetism in a topological material. Researchers at the University of Basel and ETH Zurich have found a way to flip the magnetic ...

Scientists enable excitons to surpass light to transform materials and open new advanced paths to quantum devices.

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 ...

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 ...

Powered by laser light, this tiny sail lays the groundwork for future advances in lightsail technology and the potential for interstellar propulsion. Reading time 3 minutes A team of researchers at ...

In a discovery that could reshape how we view and understand the human brain, researchers have successfully passed a laser beam through an entire human head. While it may sound like science fiction, ...

It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that’s what happened in UMD’s Energy Research Facility, an unremarkable ...

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 ...
