Do you have an example of how you'd want it to look?

The classic scanning beam slice from "Aliens" is a little different, but
I'd expect you'd want to see a slightly opaque tapered plane representing
the beam in the water medium, possibly with some interaction patterns from
tubidity particles in the water column, and then a highlight where the beam
hits the scene objects. The highlight could be done as a shader layer, a
post process on the scene Z buffer, or as a second pass with a shader.

What questions are you looking to get answers for? So many of the answers
depend on how your scene is rendered currently.
