The circuit requires approximately 6 cm 2 of board space and has no reverse-polarity or failure protection for the laser diode. The start-up time of this discrete solution is approximately 20 ms.

Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical ...

Hybrid laser diode chip In their new study, detailed in Nature, the researchers, led by EPFL’s Tobias Kippenberg, assembled a hybrid device by integrating a distributed feedback laser and a silicon ...

The laser is a 250mW diode laser bought from eBay. It’s powered through a 5 volt 7805 voltage regulator fed by a 12V battery.

A while ago, [Marco] mounted a powerful laser diode to a CNC machine in an attempt to etch copper clad board and create a few PCBs. The results weren’t that great, but the technique was promi… ...

A most critical device in an optical networking system is the laser diode, since it’s responsible for converting the electronic data to light pulses. This diode must be carefully controlled to ...

Small is the new big. China, Taiwan, and United States physicists have teamed up to develop the world’s smallest semiconductor laser. This emerging photonic technology breakthrough has potential ...

Laser staking automates printed-circuit-board packaging without damaging delicate electronics. Manufacturers of electronic components with printed-circuit boards (PCBs) have a new method for ...
