I suppose the light wouldn't have to be monochromatic, it would need carry the desired wavelength at the point of intersection and ideally at no other point along its travel. Could that be possible by directing two laser beams of any wavelength other than my desired wavelength toward each...
I am wondering if a particular wavelength could be generated by Focusing two different wavelength lasers at the same spot? My hypothesis is no, because interference only affects amplitude and not wavelength,correct? Could there be another way of generating a specific wavelength from two...
