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 ...

Normally, you think of things casting a shadow as being opaque. However, new research shows that under certain conditions, a laser beam can cast a shadow. This may sound like nothing more than a ...

"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 ...

Under very specific conditions, a laser beam can cast a shadow, challenging our traditional understanding of light. This unusual phenomenon, revealed by a team of researchers, paves the way for ...

In a recent study, researchers from the University of Ottawa have demonstrated a remarkable new phenomenon: a laser beam casting a visible shadow. Typically, photons - light particles - pass through ...

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 ...
