Hi,
I've been doing some research on building my 4w C-mount red laser and it seems that several people have killed these diodes at or below rated current. The most popular theory about these untimely (and expensive) deaths is current spikes at power up. At present there are a few drivers available with soft start but none so far are rated for the max allowable current of 5a (miniaturized drivers for handhelds). I was wondering if anyone knows of a simple circuit that could easily be miniaturized and placed inline between a driver and the diode that would offer the needed surge protection. I was thinking a simple capacitor/inductor circuit could be effective but was hoping someone with some experience and knowledge on this might offer a good schematic I could build from.
Thanks!
