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 ...

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

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

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 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 ...

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

Researchers describe a new wireless laser charging system that overcomes some of the challenges that have hindered previous attempts to develop safe and convenient on-the-go charging systems. With ...

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 ...
