If you have a really small laser or light beam that is a significant problem.
It's called scintillation.
If you diverge the light really large first, like 1meter across.
Then on the other side the effects of scintillation are mitigated as well as the dispersion of the beam is less.

Turns out that lasers aren't always the best way to go (Engineers like them).
Non-coherent light sources will penetrate those distortions you see! You will find, that except for extremely accurate laser links, LED's and non-coherent light sources make the best links.
