Laser is of prime importance in Optical memories, Fiber optic communications, Military applications, Surgical procedures, CD players, Printers etc. Various forms of lasers like Gallium Arsenide laser, ...

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.

Now researchers in Japan have reported the world’s first continuous-wave UV-B semiconductor laser diode operating at room ...

Needless to say, we’re fascinated by LEDs, laser diodes, and other blinkies. Although we can get just about any light emitting thing, the data sheets aren’t always accurate or available. For his ...

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 ...

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing ...

If you love the lasers of science fiction, rejoice because the future will be full of them, according to Nobel laureate Shuji Nakamura, co-inventor of the blue light-emitting diode (LED). The power ...

Sharp Corp and Toyoda Gosei Co have entered into a patent cross-licensing agreement covering LEDs (light-emitting diodes) and laser diodes. This cross-licensing agreement grants each other the right ...

Called RLD90QZW8, “original technology allows Rohm to reduce the temperature dependence of the laser wavelength to just Δ11.6nm – 0.10nm/°C”, said the company. “This makes it possible to narrow the ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the light has achieved desirable optical gain, laser diodes release it as ...

Modern electronics have been reaping the benefits of cheap, compact semiconductor lasers for years now. From the revolutions in CD and DVD optical data storage, through seemingly simple devices like ...
