Man could you imagine if these were 473nm diodes instead of 445nm diodes? Or better yet 488nm diodes. 750mW of 488nm would be heaven!
Well, if my math is correct, mixing 445nm and 532, should get you 488.5nm. Just food for thought, might be worth the effort. And you could even use a 150mw green module for it.

lime green?
455nm + 650nm = 552.5nm

Cool new possibilities with 445nm. Many more combinations with the 'white fusion' kit. It wouldn't be white anymore, but you could get lime green, 488nm, 430nm, and more.

<shakes head>
Mixing wavelengths does NOT give you a new wavelength.
(and you could use a 1mW module)

Well, the way I figured that out is by doing this wavelength 1 + wavelength 2 / 2

Example:
532 + 650 / 2
1182 / 2
591
i.e. yellow

In my head I thought that worked for everything, and it makes sense in that example...

Just because it "makes sense" to you does NOT mean that it is correct.

I have said this to you before:

STOP "explaining" WHY you think you were right. Listen to what people are telling you.

Your method sounds good in theory, but does not work in practice. There are way too many variables that will keep it from working in the way you described. Yes 455nm will make new colors available, but you can't just calculate the "simulated" wavelength by adding and dividing the mixed colors.

haha you are right! it was with every color I first saw.. red in the movies "predator" and "terminator", green in "alien vs predator" (..which sheds some interesting light on my childhood i guess!). now i just fire up my violet one from time to time to play around with fluorescence.. man, those colors eat up fast! :)
..all excited about 445nm, I will NEVER lose interest in this one, for sure! *smiles*

(5mw 635nm pointer? 10mw 589nm pointer? silly, not? ..must have them all!)

yep and 473 blue in IRON MAN 2 :D

As much as the 473nm blue is lovely and the science behind the crystals that produce this wavelenght is fascinating, the fact that you pay $350 for 5 mw of fragile and sensitive 473nm and a bit below $200 for a full watt of sturdy and stable 445nm, this is going to weight heavily on many people to make their decision.

It's just a matter of financial reality vs exotic blue laser that's unique. Those who can afford $300 and more will still buy 473nm LBO lasers, those who wish for blue but can't afford it will go for the deeper indigo blue diodes, I know I will... eventually.

So yes there will still be a market for the 473nm, but as mentioned in the previous posts, there will be less demand, hence higher costs. I have a strong feeling that the stage laser industry will be all over these new 445nm diodes in a flash!
