Well here is a novel one for you and one you may not have seen before. I was messing about with a crystal glass and my multiline Argon trying to make some stuff fluoresce. I shined it at the thickest part of the stem and to my amazement the laser looped 360 degrees and exited on the opposite side of the glass. This could be seen by the path of fluorescent glass.
So there you go, the first laser loop the loop.
Lucky I had the camera close
Jase.
