Knowledge of a laser beam's shape and output-power distribution is critical for optimizing laser performance. Neil Savage summarizes the latest beam-profiling products on the market. People using ...

To achieve this reflection, thin semiconductor films are deposited on top of one another, and the laser beam is further defined by an etched channel through this stack. The thickness and ...

Lacking a vault door to drill, they used a powerful laser, delidding the IC and pulsing different areas of it with the beam. How do you know when exactly to pulse? For that, they took power ...

The new high-powered microwave weapon combines many small electromagnetic waves to make one large focused laser beam — much like the Death Star from “Star Wars,” which destroyed planets by ...

Israeli defense companies are working around the clock to find solutions. One promising system is the Iron Beam, a laser-based system that is reportedly close to operational status. While ...

In one of the cooler hacks we’ve seen recently, a bunch of hacking academics at the University of Michigan researched the ability to flicker a laser at ... along with the beam’s intensity.

SUITA, Osaka Prefecture--Researchers here succeeded in zapping crop-damaging moths with laser beams, a development that has wide implications for parts of the world that suffer insect infestations.

News moves fast, and there's not always time to untangle the complex forces driving the day's biggest stories. WSJ Explains breaks down big market moves, business and economic trends, and ...

The U.S. and other countries are investing in a new way to retaliate: lasers. WSJ explains how one laser works and why the tech is so difficult to perfect.

When a Gaussian beam encounters a circular aperture, the fraction of the power passing through is equal to This rule applies to beams that are characterized as Gaussian in radial intensity pattern.

Announced on Tuesday that it will be showcasing its latest defense capabilities at the defense AUSA exhibition October 14-16 in Washington D.C., including a new Lite Beam laser-based interception ...
