I am pretty sure my 815's are 815 not 822. They where all ordered as 815 sleds. Half had the open heat sink the other half had the closed heat sink, so I tested both and the results are quite different!!!!!

Yes... now we are getting somewhere. Nice work dude. 10:1 is the bet the Typ 2 will take some more and can cough up to 500mW of raw power. Excuse me I got to go and count how many of this typ I'v got.

Cheers!

I have already squeezed another 5% out of the type 2 in the test above, simply by TEC chilling down to 10c.

To bad you can't do any wavelength measurements (or can you?) on the TEC setup. Anybody out there who could maybe take a look at that with the type 2 diode, possibly a graph of wavelength vs. temperature?

Nope. I don't have the equipment or diffraction gratings to do this.

This 815 beast is daring me to push the current towards/beyond 700mA but I don't have the nerve to kill it.

I am now testing my other Type 2 diodes in search for a matching diode. My thought is to simply PBS 2 of these for a nice tight beam of 600mW + and ditch the idea of a quad. At the end of the day, if the beam falls off my scanner mirrors whats the point?

What is curious is the fact that power output peaks at lower currents with a lens fitted. This *must* be due to some output reflected back on the die. Anyone have any input on this?

Go ahead, give it a try, be amazed like I was as I read 500mW @ 870mA and pushed it to 1000mA awaiting the kill. It survived the 1000mA so I let it live. If it fries I'll send you a new one. I'm just currious if it will power down @ currents >870mA.

Yeah, a nice dual is easier to tame. If you have a 405-G-2 lens give it a try in front of one these diodes, they even have a lower loss (<5%) than all of the red coated I've tested and the short fl gives a nice aperture beam size of <2mm and a divergence <1mrad.

Try the 405-G-2 lens with a lower loss of <5% vs. Axis @ >20%, higher loss = higher back reflection.

Hmmm. I think I have one of these, I'll try it out. Do you know were I can buy more G2's?

Either here http://cgi.ebay.de/445nm-405nm-Laser...item588dac911f
or contact Will from Laser66 direct (http://www.laser66.com/) which will probably give a better price. He's got them mounted or unmounted.

Thanks.

I tried the 405nm lens I have, I can't for the life of me remember if it is a G1 or G2. Comparied to the 660 AR glass, it gave an additional 5mW only, however the beam profile is naff. I'll grab some G2's from you link(s) cheers.

I am now thinking of grabbing a single 642nm Optinex and going dual with the 660 beast I found today. Should be ample to suit 400mW 532 and 445.

I never had a G1 so I have no idea how it performs.

i think you two guys should go into business together

every time you cooperate all of us become wiser!!!
