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 ...

In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

HALLOWEEN. WHAT HAPPENED TO SPOOKY SEASON? THE COUNTDOWN CONTINUES TO THE BIG EVENT AND WE’RE TURNING OFF THE LIGHTS AT THE ORLANDO SCIENCE CENTER. MARQUISE MEDA SHOWS US HOW AN ANCIENT FORM OF ...

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 ...

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 ...
