So then if that is wavelength at threshold, higher power might be a few nm further up?

for the heat sink Ill be taking an intel stock cooler, (75W+TDP rated) and boring a hole through the center slug to mount the laser's 12mm copper module. that should certainly be enough.

how much would you ask for a 505 case neutral one? it seems these case positive ones are going to be slightly more annoying to drive than I had anticipated.

hmmm, I do not think I will try past 1.9 amps, I cannot afford another fried diode.

I know, at 1.8 what sort of shift would I be looking at? (compared to normal the nominal 462 nm)

Sorry for the ambiguous post, I meant the M462 462nm If I could push it a bit further towards 480 or so that would be great.

so where are you all getting these diodes from besides DTR? If I could get a ~500nm one that would be fantastic, I would happily pay the full $35 or so.

I am assuming at a full dive current or 1.8-2A it would be closer to 470nm? because I think ~485 is the best blue around so if I can get it closer that is better. As for the PSU, I am replacing the potentiometers driving it, it was an amazing PSU for the price, however it does has some made...

and now it is dead, my power supply has touchy knobs, and I was a bit unsteady that day, so I accidentally completely removed the power limit, and the diode got 8v and 5 amps across it... I am now after a M462 462nm as it is a nicer blue and nearly the same power. sorry I never got beam pics up.

and those (the 505 or lower) are coming from sources other than DTR? I would rather buy from DTR though. Although I have noticed there are indeed many of these diodes on Ebay now.

I second this idea! bring the beam shots please!

if those 505s can drive that high (even 50mW is enough for me) then I think I'll get one. although that means I will have to go build a new current limiting source. (my old one was meant for working at 1+amps).

you are right, I suppose 589 is really orange, but until I see some 577 in real life, that LPS 589 is how I view a quality yellow. I am trying to find some 580nm LEDs. So then those 594nm "yellow" neon lasers are really amber. Sorry for derailing this thread. As for these diodes, I noticed...

But 590 looks yellow, I mean low pressure sodium is about a yellow as you can get. I suppose 577 would be a brighter yellow though. I feel all the way out to 600 is still on the yellow side. are there any up an coming diodes in that area?

I really like the idea of a ~480nm laser, that sky blue color is otherwise only obtainable by argon right? likely a stupid question is there any work being done on ~590nm diodes? because I really want a yellow laser that I can actually afford and is stable.
