By combining AI with holographic encryption, scientists have developed an ultra-secure data protection system. Their method ...

The U.S. Navy has successfully tested its cutting-edge laser weapon system, HELIOS (High Energy Laser with Integrated Optical ...

Tunable lasing at around 405 nm is realised with an InGaN device featuring a narrow-ridge active channel and a periodically ...

Digital currencies, communication channels, and sensitive data could be protected from cybercriminals using holograms, scientists propose.

In 2024, seven vehicles in western China each transmitted a high-powered microwave beam that converged precisely in both time ...

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

Transmitting optical information through highly distorting media has long been a challenge. Atmospheric turbulence, fog, and underwater environments distort light signals, making communication ...

Most theoretical studies on "beam riders" for interstellar travel have focused on laser beams, which are composed of particles of light called photons. Notable examples include laser-powered ...

The electrons in the beam interact with the electrons bound to the metal atoms to create X-rays," he said. "At NIF, we use the high-power laser beam instead of an electron beam to make the X-rays ...

Scientists are developing miniature lightsails that could travel at unprecedented speeds, potentially enabling interstellar ...

The UCR researchers presented a paper at a recent IEEE big-data workshop, demonstrating a new, unsupervised machine learning ...
