More than one way.
Acurate but slow: fill the scene with scathering media.
Somewhat faster: as above, but the media is contained around the beam by some
container.
Both use a strong light_source to illuminate the media.
Faked but faster: the beam path is materialised by a long conical container
filled with emissive media.
Here, the actual light is just for show as the media itself is luminous.
Using the last 2, you need to increase max_trace_level, particularly if you have
multiple beams that may visualy cross each other.
