Laser light

An area lamp with parallel light projection just like using lasers. I was trying to reflect laser light just like in the physics lab with blender but I didnt manage to find a way to do this with light sources or emissive textures, light spreads at an angle rather than parallel.

I put a texture with a roughness of 0 beneath the revolved shapes and did not manage to reflect light because the light source cannot send a parallel beam.
