By mixing the primary colors... Red+Blue=Magenta, Red+Green=Yellow, Green+Blue=Cyan, etc...

So the scanner does all that complex mixing?

Theere are different methods but mostly it's done by blanking the different colored beams independantly through computer control. With the "white light" lasers, we used an AOTF (acousto-optic tunable filter) to subtract the lines needed to make specific colors.

In a scanner, there is no prism. The resulting beam is reflected, not refracted.
So could one make a "white" laser by combining a bluray+dvd burner+cheap green diode?
and if so, would it be possible to shine this through a small lcd screen to make a projector, even though the laser is "white" but not putting out all of the colors?

No, no, and no. Red, green and blue - not red, green and violet.
No need for the LCD - that would just castrate your scarce power even more.
Just need some galvos and you get projection far superior to the results you would get with the "traditional" lcd setup.
Using the laser like a conventional light source throws away the huge advantage of a laser - that it is already a thin beam, so no (further) optics are required to manipulate and tweak the beam.

I am sorry, but it was either LED, a scam, wrong price tag or simply something else.
If it were true, I'd pay you 50$ if you can get me one.
White Laser would habe to have some kind of blue component or other strange colours.
I sure wish it would be true but this is like someone saying "oh, the local wal-mart is selling real ferraris for 500$"
