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 ...

Physicists have made a groundbreaking discovery that challenges the traditional understanding of light by demonstrating that ...

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 ...

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 ...

"Laser light casting a shadow was previously thought impossible since light usually passes through other light without interacting," study co-author Raphael Abrahao, a physicist at Brookhaven National ...

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 ...
