Best for white?

They should include throwing away you're diode under mistakes that can happen to everyone jk.
Ok I accidentally throw away my red and blue ray(from a ps3 I had) Im planning on making a white laser and now that I have to buy new diodes I was wondering witch color lasers make the best white? I would imagine that 445 would be better than 405 right?
 





i would think that 445, or 447 would be better than 405, considering that both of thos colors are close to "true blue"

Probably, but not necessarily.

Any of our common 445s can do more power output than the best 12x, and even at the same power, will be substantially brighter and more visible.

But that may no be what you need. If your green 532 is only 100mW, then maybe a 12x 405 will balancing it just fine, with the added benefit of a beam shape that will more closely match your green and red.

Ok so I been wondering this for a while (since I seen the first sticky on the 445 section)
Does the 445nm diode not have a beam shape? Is it not like the normal red and green lasers?
 
The 445's we currently have are multi mode. Without corrective optics, they output a line instead of a dot, and their 'best case' divergence is considerably higher than with single mode 405's and 650's. Or even 635.
 
If money is not the limit, a corrected 445nm or a huge 473nm would be the best.
 
Woah, I didn't know such beasts existed. DPSS, huh? Anyway, a corrected 445 still doesn't make a dot, because the prisms produce more of a rectangle/square.
 
High power non-gas laser projectors generally almost exclusively use 457nm for the blue.. At least pre-445 diode anyway, though some lower power ones use 473nm, but it's hard to find 473nm over about 1.5W.
 
This white laser isn't going to be very powerful . Anything over 150mw well do

Does a 457nm produce a "dot"? And what about a 473nm?
 
you can get a decent white with blu-ray. check out the white fusion kit. member sightfx created it and sold it off to flaminpyro. but fp hasn't started production on it yet. but he will soon.

457nm and 473nm lasers are both DPSS.. So yes, they produce 'dots' heh. You can get DPSS lasers in 657, 660, and 671nm reds too, so it's possible to build a totally DPSS 'white' rig if beams specs are what you want above all else. However, this will in no way be cheap. heh.
