Thanx for the tip about the links. The laser is a sealed tube unit, DC powered. I was wondering about the power level myself, having nothing to measure it with. The tube is drawing the correct current, but I think the power may not be up to specs because of the fact that I am not using any...

That sounds like a decent deal indeed, but I need more than 40A. I am taking the cheap way & building my own supply. I reworked a microwave oven transformer to supply 5V @100A, I have 4 100A diodes, & an 80,000µf bank of low ESR motherboard capacitors. To these I have to add a current regulator...

Thanx! :beer:

I'm interested, but what is PL?:confused:

The circuit that came with your driver is fine, & they don't come much simpler. You must leave the 15Ω resistor out, or you won't be able to drive your laser diode to full power. Make sure you test the driver with another load before you hook it to your precious diode. Set the trimmer to maximum...

Thanks for that information, you probably just saved me a diode. The situation with this diode has changed a bit; I am no longer under a time limit. When I received the diode, it was obviously not new, & was missing the shorting clip. It was listed on eBay as unused. Worse, the factory package...

I was thinking along similar lines myself, except that I need a power supply capable of >50A output. I strongly suggest that you use some form of active current limiting with your diode, because the acceptable range of voltage to any laser diode is quite small & hooking it directly to 3.3V will...

I need a quick & easy method for testing a 40W 808nm laser diode array, that doesn't require a full power supply. Can I do this with the diode test function on my DMM, if I observe proper ESD protocols? The reason for this is that I just bought a 40W Dilas laser diode array from eBay, & it comes...
