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 ...

Newport has developed a diode laser current driver circuit with noise characteristics that it says are as much as 10 times lower than currently available. The company also claims that the circuit ...

The laser is a 250mW diode laser bought from eBay. ... The schematic for the circuit is given at the end of their video, which you can see after the break.

The value of R1 is determined by the maximum laser current required (in this case, 250 mA), adjusted by the laser diode's typical forward voltage of 2.0 V as given on the datasheet. Solving for R1 ...

We work closely with our partners to offer a comprehensive range of laser diodes and can assist in the design-in of appropriate laser drivers alongside our laser diode products. iC-Haus laser diode ...
