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 ...

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.

BMW develops laser light for the car. Following the introduction of the full LED headlight, laser light is the next logical step in the development of vehicle headlight technology. BMW is planning ...

Biotium announces the release of the next-generation Gel-Bright™ Laser Diode Gel Illuminator. In partnership with Biotium, light and optics instrumentation company OMEC Medical developed the gel ...

Before going into exterior lighting solutions for all things automotive, it's necessary for us to remember that – in the olden days of black and white everything – horse-drawn carriage lamps used ...

Color digital laser and light-emitting diode printers are very similar. Both can print your business documents relatively quickly by melting toner to the paper, and both use a photosensitive drum. 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 ...

A German project has revealed 400W infra-red laser diode bars for welding metals. “About 10 years ago, the best laser bars achieved a power of 200W with an efficiency of about 63%,” according to Osram ...
