So this might sound like a stupid question but if we can achieve all the colors of the visible spectrum with high grade optics and beam combineders why can we make a black laser beam?
what i understand true black is when no light is reflected of the surface/ materiel
that would mean you cant make black with light.
some one correct me if i am wrong
I think you mean Heisenberg's uncertainty popsicle.
Well, bobhaha pwned everyone with the wave cancellation theory in that other thread.
