that effect is derived from a high speed rotating polygon multifaceted mirror on one axis, with a laser bouncing off it

OK, I googled trying to find what this is about and can't find it yet, what is a liquid fan?

I can find lots of diffraction gratings on ebay, but not sure what you are after:

Maybe draw it instead of trying to explain it?

I think I understand now, several laser beams all lined up together in a fan-like orientation. I've never seen one like that.
