Is it possible that if you have 2 ultraviolet lasers, that are invisible to the human eye, and if you aim their beams to intersect at some point, that the place of intersection will show a lower visible wavelength of light, caused by interference of the light freqency? Can any other form of heat or energy be generated at the intersection?
If so, can someone provide a link to the explanation? I am curious about this.
EDIT: I should add that the 2 lasers would have different light frequencies while they are both invisible to the human eye. So, I am wondering about interference between light freqencies.
