Crystals incorporating a dash of light-absorbing dye can be sliced, etched or embossed by a low-energy laser beam 1. Scientists are constantly seeking new ways to manipulate materials with light.

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 ...

A 3D printer that uses lasers to build up an object in any order, rather than layer by layer, could produce more advanced designs than is currently possible. Existing 3D printers work by depositing ...

Laser hacking. If there's one phrase that says we're already living in the future I imagined as a kid, it's laser hacking, or to give one method its more technical term, "laser fault injection". While ...
