Does anyone know how to make a realistic visible laser? I've tried a small spotlight with very little spread, but you can't see the beam. I've tried to add some fog effects to no avail.
I also tried a glowing column, but it radiates light in all directions.
Any ideas?

have you tried shooting the spotlight through a cylinder with fog? You may have to make the fog very dense: 300% or more, you can set your light to a strong intensity, and you can set the light's full intensity distance to the full length of the cylinder.

it works just fine for me here. Can you tell me more about what you are doing? I just set mine up in a blank scene, because I don't know what else you are up to...

I tried to make the fog a bright green. I just have a spotlight pointed at one of the ends.
I'm making a laser sight. So, the spotlight and column are inside a small cutout in the center of a cylinder.
I did edit some of the spotlight properties though (light source radius, full intensity angle, etc..). Maybe I messed up some of the basic settings.

so, I don't understand your file. Are you rendering from the camera in the scene?

well, tell me what you think of this.
I set up a shape which is a cylinder filled with fog, no other texture, and shot a narrow-beam spotlight though it. I put that shape in your scene in 2 places, probably not where you intend

I'm going to give you a second,more subtle one in just a bit.
the one thing I want to be sure you understand is that I manipulated the light's full intensity distance. That is a zone you can set on a light where there is no drop-off. I set that to the full length of the cylinder. If you make the cylinder longer, you may need to make the full intensity distance longer as well. That is in the object properties window for the light.
another file is coming in just a bit...

Is a laser spotlight possible?
