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 ...

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 ...

When a laser experiment fails to produce the expected flash of light, most researchers would assume something went wrong with the hardware. In this case, the missing signal turned out to be the most ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how ...

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 ...

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, ...

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 ...

Long tubes, strong magnets, and bright lasers. Is that all it takes to entice the shyest particles in the universe to reveal themselves? Physicists working on the ALPS II experiment certainly hope so, ...

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 ...
