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 ...

Efficient 1.5 W CW and 9 mJ quasi-CW TEM00 mode operation of a compact diode-laser-pumped 2.94 µm Er:YAG laser Sheaumann has developed the first commercially available diode-laser-pumped continuously ...

Our expert, award-winning staff selects the products we cover and rigorously researches and tests our top picks. If you buy through our links, we may get a commission. James has been writing about ...

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 ...

Rarely a week goes by that some company doesn’t offer to send us their latest and greatest laser. You know the type — couple of aluminum extrusions, Class 4 diode flopping around in the breeze, and no ...

[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 ...

Australia-based semiconductor developer says its 405nm model is approaching commercial specification. Applications include welding, cutting, sensing, 3D printing, displays, and AR/VR. Sydney, ...
