Ultrawide-bandgap semiconductors—such as diamond—are promising for next-generation electronics due to a larger energy gap ...

Epson has expanded its home cinema range with two "4K Pro-UHD" laser projectors, the EH-QS100W and EH-QS100B. Both promise to ...

Researchers have built a deep-ultraviolet microscope to study hard-to-analyze materials like diamond, offering a new way to probe their electronic and thermal properties at the nanoscale. This ...

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

One of the coolest things I saw at CES 2025 was Hisense's mini laser TV projector, which is an interesting prototype that's ...

Finally, there’s a risk that red light therapy may not work for you. “The amount of weight loss is modest at best,” Dr. Ali ...

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 ...

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 ...

Laser therapy, also known as Low-Level Laser Therapy (LLLT), uses light to treat pain and inflammation. The light energy from ...

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

A team of Caltech scientists has made the first experimental measurements of laser-induced motions of miniature lightsails in the lab.
