How to use negative feedback to regulate output power from a laser diode using a simple, single op-amp based circuit ...

Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at ...

In his endless quest for more optical power, [Les] happened upon a paper describing a simple driver circuit that can dump massive amounts of current into a laser diode to produce far more optical ...

In addition, power control for the laser diodes is performed by automatically adjusting the power source to save power and minimize heat dissipation. Contains various protection circuits such as laser ...

The transmit side of the circuit is rather simple. An op-amp circuit acts as a constant current source, biasing the laser diode. The transmit signal from an Ethernet cable is then added in as ...

--(BUSINESS WIRE)--KYOCERA SLD Laser, Inc. (KSLD), a world leader in commercialization of laser light sources, is introducing its new high power 5 watt blue laser diode products for ...

Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but the laser diode generates a smaller beam that is easier to couple with the smaller core of singlemode fibers.
