Scientists Demonstrate Laser-Induced Shadow Phenomenon

A groundbreaking experiment shows that under specific conditions, a laser can cast a shadow, challenging traditional optics.

Researchers from Canada and the U.S. have shown that a laser beam can cast a shadow by blocking another light source.
The experiment was conducted using a green laser and a ruby crystal, which altered the absorption of a blue laser to create a visible shadow.
This discovery challenges the conventional understanding that light passes through light without interaction.
The phenomenon could have implications for technologies involving optical switching and precise light control.
Future research aims to explore different materials and laser wavelengths to further understand and utilize this effect.
