What behind the apparent abrupt termination of a laser beam into a
clear night sky, rather then a gradual fade out ?

Thanks


My _guess_ would be simple perspective. As the scattering point gets far
enough from you, your line of sight overlaps the divergence of the beam for
that and any larger distances.
