Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

UPTON, NY—Lasers are intense beams of colored light. Depending on their color and other properties, they can scan your groceries, cut through metal, eradicate tumors, and even trigger nuclear fusion.

Scientists get peacock feathers to emit laser light after adding dye and green pulses, revealing surprising biophotonic ...

Scientists have made small red and blue lasers for years, but other colors have been a challenge. Researchers have filled an important technology gap by creating orange, yellow and green lasers tiny ...

Just when you think you've seen it all, researchers claim to have developed a way for people to see a color the human eye has previously never seen before. They're calling this new shade 'Olo.' I want ...

Researchers have developed a compact light source that generates dozens of high-power wavelengths, paving the way for a new generation of data center hardware and portable sensing technologies.

For years, scientists have fabricated small, high-quality lasers that generate red and blue light. However, the method they typically employ — injecting electric current into semiconductors — hasn’t ...
