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 ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

"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 ...

Light's shadow: Researchers showed that a laser beam can sometimes act like a solid object and cast a shadow that is visible to the naked eye. In the picture, the shadow appears as the horizontal line ...

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 ...

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 ...

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 ...
