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.

What you say is not possible with interference. Interference of light does not produce new colors of light. Light would have to scatter inelastically off of some molecules to produce a down-shifted frequency (Raman scattering or some type of wave-mixing phenomena). The point is, the light should interact with matter to change its frequency.
