Military researchers are now proving that drones do not always need to carry their own fuel or batteries. In recent tests, aircraft have stayed aloft while being fed energy from the ground through ...

The energy sent is low-intensity, invisible infrared light, which allows ground-based solar projects to generate power even when the sun is not shining. Unlike other concepts, Overview’s wide-beam ...

Calculating laser power density What is a LiDAR point cloud? Wide array of applications for lasers. LiDAR (light detection and ranging) can measure the distance of an object (measuring the time for ...

A tiny device can control laser light very precisely while using much less power, making it possible to build bigger and ...

In a move that sounds like the wildest of science fiction, DARPA has announced its new Persistent Optical Wireless Energy Relay (POWER) program that plans to use lasers relayed by airborne platforms ...

Researchers from the National University of Defense Technology have developed a novel composite fiber Bragg grating using ...

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 ...

To address these challenges, Nuvoton Technology has introduced a compact violet laser diode delivering 1.7 W optical output ...

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 ...
