A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but ...

The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...

Ever wonder why projector systems and televisions doesn’t use laser illumination? It isn’t for safety reasons, and it isn’t for efficiency reasons—laser diodes have efficiencies ranging from 30 to 50 ...

[Johannes] has been reading Hackaday for years but this is the first project he’s tipped us off about. It’s a laser engraver built from a DVD burner diode (translated). It turned out so well we wonder ...

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 ...

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 ...
