Please define the orbital angular momentum of light(i.e. twisted light) and how it differs from the regular angular momentum of light. And how does it differ from circularly polarized light? Please explain in a way I can get a mental image of what these things are. I've read that it is a relatively recently discovered fundamental property of light (about ten years ago or so) and it's very interesting but I can't get a mental picture of it and how it differs from the other angular momentum of light. I saw an article that someone made dust particles move in a circle when illuminated by a beam of twisted light. Is there a relatively inexpensive way of doing this as a class demonstration? Thanks a lot!
