What exactly do you mean by "laser line"? A laser beam that is spread
out to make a long line on a surface, as is used in some laser levels?
The visible line of scattered light a laser makes when travelling
through a scattering medium? The radial lines you some times get when
you take a picture with the laser going into the camera?

In what way is this not enough? It's difficult to give a better solution
when you don't say why the old solution isn't good enough.
Assuming you want a laser beam through a scattering medium: the simplest
and most accurate way is with photons deposited in scattering media. The
optics.pov demo scene gives a good example of this. For a laser, it
would be better to use a parallel cylinder light instead of the
halogen-like spotlight in that scene, but the technique is the same.
