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 trials).

Adding to the PLD-CH chassis-mount series linear laser diode drivers is a 12.5A model, the PLD12.5K-CH. Like other members of the series, it offers single-supply operation from a +5 Vdc supply and, ...

SAN FRANCISCO--(BUSINESS WIRE)--Opnext, Inc. (NASDAQ:OPXT), a global leader offering one of the most comprehensive families of high power, low operating current red and infrared laser diodes, today ...
