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:

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

Is that you Tony? Is your avatar showing it?

thanks so much for the help laser project, liquid fan DG at nova was like many laser line beams on a single line. i wish i told what i am trying to tell that is the best effect i have ever seen. was perfect with green lasers, but i lost it :cryyy:

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.
