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 discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

1960: Physicist Theodore Maiman uses a synthetic-ruby crystal to create the first laser. Maiman began tinkering with electronic devices in his teens and even earned college money repairing appliances ...

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 ...

In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

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 ...

I was reading through some cool facts about lasers to put on my Instagram and other social media platforms and I find out some pretty cool stuff. Did you know, back in the day, the power of the first ...

Exclusive to optics.org: Innovative intra-cavity design has produced a continuous-wave ruby laser, with other novel sources set to follow. A new source developed by Germany-based laser supplier ...
