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 ...

A group of scientists have created a high-power laser beam that they claim lightning will follow for a period of time. Physicists have published a new study in the scientific journal Nature Photonics ...

It's double-barreled, it uses lasers instead of LEDs, and it's machined from a solid block of 6061 aluminum alloy. Come meet the Lumitwin DL700 flashlight, which belts out two converging beams up to a ...

Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible. Michelle Starr is CNET's science editor, and she ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

Since their invention in 1958, lasers have become a vital tool for manufacturing products as diverse as cars, musical instruments and computer chips. Lasers not only offer precise drilling, cutting ...
