The ability of new blue-light semiconductor lasers to better perform precision cutting, patterning or welding of copper will make electrical and electronic component manufacturing cheaper and more ...

A semiconductor laser that emits light in the 400-450 nm range. Although it was very difficult developing blue lasers, which emit smaller wavelengths than other colors, blue lasers became ...

co-recipient of the 2014 Nobel Prize in Physics for the invention of blue light-emitting diodes, founded Blue Laser Fusion in Palo Alto, California, in November. Partners include Hiroaki Ohta ...

A research team from the Department of Chemistry at UNIST has announced that they have identified a novel pathway through ...

Learn more› By Kaitlyn Wells and Zoe Vanderweide If you believe the hype, blue-light blocking glasses will prevent headaches, decrease eyestrain, and help you sleep like a baby. But do they work?

However, such systems cannot match the small size and low-cost benefits provided by semiconductor laser diodes that directly emit green light. The first attempts to fabricate blue and green diode ...

However, do blue light glasses actually work and make a difference for those of us who stare at screens for several hours? The answer isn't as straightforward as yes or no. All visible light we ...
