Was done here (though not confirmed that it was a PLT5-510): http://laserpointerforums.com/f45/anyone-spectro-d-plt5-510-a-97677.html#post1430272 510nm exact.

I went ahead and graphed the data you took. Seems like the "safe" current is somewhere in the yellow zone, maximum 250mA or so. The efficiency slope changes at 136mA and again at 258mA. I'll probably run mine around 50mW/160mA, should be plenty of power to go with my red and blue diodes :)

Cool, I'll look forward to that. Still waiting on receiving the diode so no worries on waiting.

Anyone have power vs. current data for the PLT5-510 diode from Osram? I did some heavy searching and only found passing mention of this diode, but it seems to be single mode (though low power), and I plan on making an RGB laser with one of these, an SOC red, and a PL-450B blue (which I found...

Same deal, focus it down to about a 1mm spot or so, and blow on it lightly and periodically once it starts glowing orange.

Have you tried blowing on it lightly, like kindling a fire (because, really, you are). Works pretty well for me, though I can only light a few materials (cardboard, candle wicks, and maybe a couple others).

It's not really worth it. The three wavelengths are all at different focal points, so you would have to refocus it for each color. A dichro based multi-wavelength laser would probably be a better option. However, that brings me to the point that the PS3 sleds are quite useful for the dual...

I was referring to the 650nm. I run the SF-AW210 405nm at around 130-150mA. I don't remember since it's been almost a year, but I'm pretty sure I just used a pair of pliers and a vice to break the heatsink. It's a brittle alloy of aluminum and magnesium, most likely.

Did you ever get that sled from PSXboy? Same quality as the more expensive source?

Heh, just wanted to make sure this got out there. That idiot posted his video as a reply to my 445 vid. Not sure why he thought I was jealous because he "got some balls". I'll be enjoying my vision and my lasers longer than that guy will, I reckon.

Well I'm not sure if this is the right section to post, but I can't let this one go, this Youtube has absolutely no concept of the danger that a 1W 445nm laser posesses: YouTube - Dangerous blue laser projector He pointed it while on a busy highway (2:00), scanning some houses in the background...

I've lit about 6 different candles with my ~1-1.2W (just turned it down recently, still ignites cardboard in about 15s): YouTube - 445nm 1W Laser Lighting a Candle The key for me is blowing on it lightly every once in a while to stoke it and give it some oxygen, just like if you were starting a...

I really hope some company finds a use for these and we find a source for them. I'm still waiting for direct green diodes, but I'd love a 750mW single-mode blue; the "dot" on my 445 is pretty useless at >5 feet away.

The SF-AW210 definitely has a SOC diode. Here's a picture of the two I got out of my sleds: (click to enlarge) I run mine at around 200mA, here's some PIV plots if you'd like more info: http://i53.tinypic.com/16lk969.jpg

Here's my extracted diodes (the short open can ones are the reds). I run it at 150-200mA, but it can handle a bit higher. And here's a couple PIV plots:
