We tested four super bright flashlights that range from a laser-powered flashlight that shoots a beam over a .5 mile to a ...

As the demand for digital security grows, researchers have developed a new optical system that uses holograms to encode ...

The idea of traveling through interstellar space using spacecraft propelled by ultrathin sails may sound like the stuff of sci-fi novels. But in fact, a program started in 2016 by Stephen Hawking and ...

By combining AI with holographic encryption, scientists have developed an ultra-secure data protection system. Their method scrambles laser beams into chaotic patterns, making decryption impossible ...

"Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from swinging by the sun for ...

"Your dentist's X-ray machine creates an electron beam that is crashed into a heavy metal plate; the electrons in the beam ...

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate.

Laser cleaning isn’t quite ubiquitous, but it’s gaining a foothold for applications like paint and rust removal as well as ...

A team of researchers at JILA, led by Professors Margaret Murnane and Henry Kapteyn, has developed a groundbreaking ...

Another benefit is the higher power output. Multimode laser diodes are able to generate higher optical power, making them ...
