Two laser beams intersecting at 53mm after passing through a 17mm focal length lens is more than weird. It is certainly a novel way to double the intensity of the light over a very limited reqion but this optical design comes with consequences. In this session we investigate the intensity properties of the beam at the intersection point and how that can be best expoited by certian types of engraving.
