For the beam itself, you can create it using a long thin tube with an opening at one end and a small light source at the other end. Kinda like this:
The light source needs to be very small and very bright for best results. Of course, it needs a volume fog or some other medium to be visible, and it only really works for short-ish distances before the light beam begins to disperse... but it is a quick and easy way to create a laser beam that interacts with the environment.
If you need a really long beam with no dispersion and don't care about interaction, you could always fake the beam entirely by using a long luminous tube and then play with the transparency texture until it looks more natural

Use cilinder with emission texture (low power and check surface brightness) and use opacity with noise, and put this noise to non uv projection like box and in texture Proj set world space position in position tab - this make illusion of foggy enviroment when you move beams - you also can slowly animate noise if beam don't move
