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 ...

Interfacing laser driver circuits with commercially available laser diodes at high data rates can be a complicated and frustrating task. This application note is intended to briefly address this topic ...

Laser diodes can destroy themselves in a few nanoseconds, so testing the response and stability of a feedback-stabilized laser-diode driver can be expensive. The simulator circuit in Figure 1 shows a ...

Comparison of a 5W laser, 10W, and 20W diode laser. All these machines have their pros and their cons, but this is a quick comparison of their ability to cut and engrave. I do not have a lot of ...

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 ...

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 ...

If there’s one lesson to be learned from [Aled Cuda]’s pulsed laser driver, it’s that you can treat the current limits on electronic components as a suggestion if the current duration is measured in ...
