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 ...

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 ...

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 ...

Light normally makes other objects cast shadows – but with a little help from a ruby, a beam of laser light can cast a shadow of its own. The crucial ingredient was a ruby cube. The researchers hit ...

After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, scientists decided to experiment in real life — and found that laser beams ...

Rakesh Malik on the importance of embracing the dark side and using shadows to their full extent. In both photography and cinematography, the focus tends to be on exposure. That should come as no ...

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 ...
