Materials Science: Will UV Lasers Beat the Blues?
Robert F. Service
SAN FRANCISCO--Over the last few years, researchers worldwide have been racing to commercialize chip-based lasers that emit blue light, which could increase fourfold the amount of information packed into today's CDs and CD-ROMs. But at a recent meeting of the Materials Research Society, scientists reported creating a new type of laser that generates even shorter wavelengths--ultraviolet.
