A team of scientists has found that the narrow beam of a laser can cast a shadow — a surprisingly counterintuitive finding.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Technical University of ...

The blue laser light was directed at one side of the ruby, where it passed through and cast a cool glow upon a screen, while a narrow beam of green laser light passed perpendicular to the first ...

The effect occurs because the green laser increases the optical absorption of the blue illuminating laser beam, creating a matching region in the illuminating light with lower optical intensity.

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 ...

The green laser increases the crystal’s ability to absorb the blue laser beam. which creates a matching region in the blue beam that appears as a shadow.

PowerLight Technologies says it's joined a team headed by Blue Origin to design a power beaming system for charging up robots on the moon.

The Pinellas County Sheriff's Office arrested a 70-year-old man who deputies say shined a laser pointer at a helicopter aiding deputies in a burglary investigation.

The move from infrared to blue laser processing will improve the precision of copper component assembly, particularly for electric cars, say scientists.

In their high-energy state, those electrons can absorb blue light from the second laser. The green laser beam thus behaves like an object, blocking the blue light and casting a dark line across ...

Crime Houston helicopter laser incident ends in arrest, sheriff warns The Harris County Sheriff's Office helicopter was on patrol when the cockpit was hit was a bright blue light, the sheriff said.

Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow ...
