An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

Nagoya University scientists, in cooperation with Asahi Kasei Corporation, have succeeded in designing a laser diode that emits deep-ultraviolet light, according to research published in the journal ...

Asahi Kasei Corporation succeeded in designing a laser diode that emits deep-ultraviolet light. The laser diode emits the world’s shortest lasing wavelength, at 271.8 nanometers (nm), under pulsed ...

Researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses. Nagoya ...

Last August, the town of Irondequoit, N.Y., near Rochester, opened its $13 million, 37,800-sf public library. The entry lobby is illuminated by organic light-emitting diode (OLED) fixtures, one of the ...

Osram Opto Semiconductors has introduced the first compact laser multi-chip package. The PLPM4 450 module can pack up to 20 blue laser chips into a single "butterfly" package for projection ...

When we think about the onward march of automotive technology, headlights aren’t usually the first thing that come to mind. Engines, fuel efficiency, and the switch to electric power are all more ...

Japan’s Shimadzu Corp has developed a blue direct diode laser (DDL), providing what is claimed to be industry-leading brightness levels. The 10W-type laser was exhibited at InterOpto 2013 at Pacifico ...

With optoacoustics having "come of age" as an imaging technique, the hottest topics in the sector now revolve around development of effective clinical systems for human applications. Suitable laser ...
