Do you think the Laser Community will be seeing new wavelength's soon?

I don't think other colors will happen soon (cheaply, that is - for $$$$ you can get almost any color you want) but I hope I'm wrong. There needs to be a major consumer electronics demand for a diode to get cheap enough for us.

Maybe 47X but I'm not sure what the demand for those would be.. Not very convinced about them being better for projectors - would make deep blue very hard to achieve.

Yes, you'd be right on that I think. 450 is better for colour mixing.
And anyone who needs a 470+ or 488 for sciency stuff or whatever can probably afford to pay for a diode or get an argon.

520nm is more ideal for color mixing than 530nm...
This is what I read on PL
When you obtain a color by mixing 2 primary colors, the result can only be situated on the straight line connecting the two points (wavelength of each primary color).
As you can see the yellow shade is really thin in the color gamut (= hard to obtain because of its high gradient who shifts the perceived color by human eye). When you shorter the wavelength of the green light source, the result in yellow decrease. You lose the "saturated" color character.

This is why it is impossible to obtain such a beautiful yellow as OPS laser @t 577nm .


In short ;
520nm diodes are nice for modulation, alignement, cold hues (and maybe price in a few months) BUT give poor results in warm hues...

So it would make more sense to Use a 520 diode in a projector as its divergence is similar to the blue diodes and red ones but you will get less warm colors
TVs with yellow pixels don't seem much different because they use the proper wavelengths of R, G, and B the yellow pixels were just something to throw in to increase the cost of the tv. a yellow diode (or a 530nm diode) would actually improve the color profile of the projectors
