I think Osram uses GaN (InGaN ???) semiconductors to make 520nm laser diodes... Osram set for green diode ramp in 2012 mentions them using it in this paragraph: "One of the toughest challenges with the gallium nitride (GaN) semiconductor material system used by Osram is to push..." not sure how reliable the source is, but there was a Scientific American article back in April 2009 saying laser manufacturers were looking into m-plane non-polar substrate cuts to get GaN layers to produce a green laser diode...

Good show, Burn. This thread is coming together nicely.
Speaking with MarioMaster on Laserchat, he mentioned having a 10 or 12 line argon, though the PSU went to shat the day after he got it. So he might be able to add some decent argon coverage once he gets it fixed. Also has an air cooled Krypton, so he can contribute that as well.
If you are adding useful information, or asking a question related to the thread, I think posting to an old thread is better than creating a new one. Not everyone agrees, but thats what it is to be individual, we don't all see things the same way, a good thing. All of that said, I agree, in this case you didn't add anything to the thread which would warrant bringing up an old one. However, I would have never seen this thread if you hadn't, sometimes a bad thing can be good because I am very interested in page 1
