That's what it looks like... was it soldered on or glued?

Re: RED & 808nm 1-5 WATT LASER DIODES & MORE CHEAP!!~ It's ok. I would be interested to hear more details though when you get time to test them thoroughly. Heruursciences: I am still interested to know if you have any of those QCW 20W 9mm diodes I mentioned before.

I got a couple like that too, but they seem to be dead...?

Re: RED & 808nm 1-5 WATT LASER DIODES & MORE CHEAP!!~ HIML9, your last post should have gone here, however, interesting results... I actually got 2 reds in the first three grab bags, but they were broken. they emitted all the light from the top of the die instead of the front...

Perhaps he test them himself? His prices are great, but I will admit that getting information out of him is like pulling teeth...

Re: RED & 808nm 1-5 WATT LASER DIODES & MORE CHEAP!!~ He said he has had problems with the PM system here. You might have better luck contacting him through ebay...

I agree. I didn't think he got that stuff from Boston Laser, but if not, how could it be so cheap? Wherever he gets it, I'm glad he's here because I couldn't afford it anywhere else. Thanks Chris! P.S. I'm glad you came back. I had to search google for the first page of this thread and click...

Thanks!

Hey, now that I finally have money to order, your site says you only have a couple phr and lpc sleds left. When are you getting more in?

Also strange, most of mine seem to have lasing thresholds from 400-600mA. A couple of them seem to have a threshold at... 800mA? And a couple more seem to have a threshold at about an amp. At first I thought these were just weak, but Boston Laser says they have 20W Pulsed 9mm diodes that have a...

I totally know how that goes. By the way, he's still selling, just not here. Why? I don't know. His reasons don't really make sense...

I've gotten three grab bags so far, and I haven't found one yet that is NOT case positive. It is possible that some are, but I have not found a red one either.:cryyy: I just test using 200 to 800mA of current. I also test them before with a multimeter to check polarity and voltage drop. Normal...

That's what I do. If you have the polarity inverted, it will say it is an open circuit. If you have the polarity correct, it will give you the voltage drop.

You've stopped selling on LPF?!?! Did you get my PM about another order?

Well, I've gotten three grab bags and haven't gotten a single red.:cryyy: I have gotten to where I can tell an 808 just by looking at it though...

How much is the bare heatsink?

Hey jayrob, What are the dimensions of the pocket mini heatsink?

Duly noted. I just think it's interesting that most of mine seemed to be 2W or greater when Mariomaster didn't get any above 1W. That's why I was questioning my test results.

Nothing above 1 watt?? If I did my testing right, most of the ones I got had thresholds at 400mA, 500mA, or 600mA. According to your chart, that would be 2W, 3W, and 4W? Am I doing something wrong or am I just lucky?

As long as there's no IR filter, I think a digital camera should at least see some IR even at 1500nm, IMHO. I only got one diode that didn't show anything through my digital camera and it is certifiably dead. It does get warm, but there is no light and no power with a power meter.
