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 ...

Lasers (Light Amplification by Stimulated Emission of Radiation), which produce an intense and highly directional beam of light ... Although OSHA has not adopted any general industry laser specific ...

Laser cleaning is a process where a laser beam gets emitted from a laser-cleaning machine. And this handheld device will always be pointed towards a metal surface with any surface contaminants.

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 ...

Here’s a surprisly simple way to build yourself a laser-based listening device. It consists of two modules, a transmitter and a receiver. The transmitter is a set of lasers, one is visible red ...

Here's how it works: When you hit print, the printer's laser beam "draws" your document onto a drum inside the printer. This drum is coated with a material that becomes electrically charged where ...

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 ...

While not as much of a watershed moment as when Israel can finally deploy its Iron Beam laser defense system, the Lite Beam is still a powerful example of Israel succeeding in using layers ...

The word laser usually conjures up an image of a strongly concentrated and continuous light beam. Lasers that produce such light are, in fact, very common and useful. However, science and industry ...

Israel expects its “Iron Beam” laser defense system to be operational within one year, saying it will bring “a new era of warfare” as it engages in a war of drones and missiles with Iran ...
