at the moment that is as close to orange as you can get without a RGB setup, that is 3 lasers, a red, a green, and a blue that are used at diffrent power levels to "mix" the beams into other colors, but if you think the 2mW yellow is expensive, you wont want to imagine a RGB

If you want to know my opinion, "yellow" lasers are orange. Maybe yellow-orange or orange-yellow, but they definitely don't look yellow. Yellow DPSS and HeNe is not cheap by any measure, but they're orange enough for me. On the other side you have red-orange 635nm and common HeNes, but the "yellow" lasers are more orange to me than that.

I love the blues myself so i'll wait until the prices go down when blue ray is well established.
The only small orange lasers I know of are HeNe lasers, but they are not pointers, unfortunately.
The yellow 594 wavelength is neither yellow nor orange, but a beautiful amber color; if you light up a quartz crystal with it, it looks like transparent gold.
I don't see why a yellow or orange laser pointer could not be made by craftily blending the beams from red and green pointers, if one did not mind a somewhat larger device.

I dont see why with the all of the stuff we know today why the world cant make like a WLA lol World Lasers Ass. or something to update the lasers to colors like orange and black and to have power like 100W for a pointer lol. Or just lower the prices ;D

A black laser cannot exist - as black is the absence of color ! you can get a deep violet, but the black is a no-go !
That's not a threadjack, that's a threadwreck! ;D
There are several reasons lasers aren't readily available in colors such as orange (it's not that you can't get one, you can, but it will be expensive).
1. Demand. There has to be a useful purpose for the wavelength in question to create enough demand to enable a manufacturer to bear the costs of R&D and tooling up to build the lasers. Red diode lasers are only cheap because they are used in so many products. Blue and green DPSS lasers are cheap because they are derived from the efficient 1064nm Nd:YAG/glass lasers that find wide use in industry and science/R&D, and also because they can replace other more expensive lasers such as argon ion. For mundane uses such as light shows, orange can be generated by RG mixing, so orange lasers are unnecessary.
2. Physics. For gas lasers you are stuck with the transitions nature gave us. For diode lasers there appear to be more options, but insufficient demand kills that. For the DPSS lasers there are a limited number of crystal combinations available, and the colors that can be made are determined not by the desire of the end user, but by the properties of the crystals. If those colors happen to match what you want, then great. If not, you have to do more tricks, like sum-frequency mixing of the ouputs of multiple crystals, to get the "in-between" colors.
3 Efficiency. Not all colors can be produced as easily in quantity, because of varying degrees of efficiency in the conversion process.
4.Expense. Even if there is demand, if the desired color is too expensive to produce, or cannot be produced at high power levels, it will not see widespread use and will remain "unaffordium" to most.
(okay, contributing to the trainwreck ;D - you can bounce light off of plasma. That's how those guys running the petawatt research laser focus the pulses, because there are no optics that will withstand the pulse. The pulse hits the surface of a polished concave glass "optic". The energy is so high that the surface layer immediately becomes a plasma, and does not have time to expand during the ultrashort period of the pulse. The remainder of the pulse reflects off that dense plasma layer and onto the target.

WOW, that is amazing!

Are you like really smart or did you just copy and paste that?

Rangarok is just really smart (or we're all really stupid, but lets not go there
