Physicists are learning to carve laser beams into intricate shapes that can grab hold of electrons and push them with a ...

A NASA laser just fired successfully in a deep-space test. On Nov. 14, NASA picked up a laser signal fired from an instrument that launched with the Psyche spacecraft, which is currently more than 10 ...

Coherent beam combining (CBC) in fiber laser systems represents a transformative approach to surmount the inherent power scaling limitations of individual fiber laser emitters. By precisely ...

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 ...

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 ...
