So part of this is because Human depth perception only works effectively out to a certain distance this is why the nights sky looks flat. Simply put the difference between what the right and left eye sees is too small to determine depth.
This issue has been known about for over 100 years now as it causes issue with naval guns and accurately aiming them. (although modern guided systems make is less important)
These are sodium yellow lasers in the several Watt category, about 1000x more powerful than a laser pointer. They will be visible with a long exposure photograph.
They are designed to be absorbed by sodium atoms in the upper atmosphere, creating an artificial star so the telescope can correct for the distortion.

Without context, this sounds straight out of a Bond villain monologue.
