In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

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 ...

Those models give the simulated laser beam its own shadow because they treat it as a solid object instead of a ray of light. During a lunchtime conversation about this quirk of the modeling system, ...

Scientists have demonstrated that light alone can reversibly control magnetism in a topological material. Researchers at the ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet ...

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 ...
