    Laser Diode Emits Deep-UV Light

    Article obtained from Photonics RSS Feed.

    Nagoya University researchers, in cooperation with Asahi Kasei Corp., have succeeded in designing a laser diode that emits deep-ultraviolet light, according to research published in the journal Applied Physics Express.

    “Our laser diode emits the world’s shortest lasing wavelength, at 271.8 nm, under pulsed current injection at room temperature,” said Professor Chiaki Sasaoka of Nagoya University’s Center for Integrated Research of Future Electronics. Sasaoka explained that previous efforts in the development of ultraviolet laser diodes had managed to achieve emissions only down to 336 nm.

    Laser diodes that emit short-wavelength UV light could be used for disinfection in health care, for treating skin…
