Scientists Unveil Lasers That Cast Their Own Shadows
TL;DR
New research demonstrates that a laser beam can cast a shadow under specific conditions using a ruby crystal and certain laser wavelengths. This occurs when a green laser alters the crystal's properties, increasing its absorption of a blue laser beam and creating a shadow effect. This phenomenon could have potential applications in using one laser to control another.
