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.
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.
