You can focus it to a point, but there's nothing you can do that will fully collimate the beam, i.e. it will always diverge.

In fact, if the particles in the jet are fast enough, they can collimate themselves quite nicely due to relativistic effects.

Collimation synonyms

There are two nouns morion kind of helmet, does not concern us here (it is probably from Spanish smoky quartz, has an interesting etymology: it is from a Latin word here about collimate, from an erroneous reading of Latin collineare; I wonder if there is a list somewhere of words with similar histories?

In 2005 they used high-power ‘Luxeon’ LEDs, i.e. non-coherent sources, combined with a large Fresnel lens to collimate the non-directional light emitted, and managed two-way audio communications over a distance of 160 km (100 miles!) between mountaintops in Tasmania.

A slight vacuum is pulled behind an aluminized mylar plastic film to create a very large convex mirror to collimate the visual system in many aircraft simulators.

Using a light pipe [such as fiber optic] won't help to collimate your beam, total internal reflection means that as the angle of incidence = = the angle of reflection, the light entering the pipe at random angles will exit just as randomly.
