RE- your picts from Aug 15th---- taking a second look it looks like the lower pict was taken first and the burn pattern is in a crescent shape. Glass tube sometime have a hollow beam at low powers, altho it looks like a pretty powerful beam in the pict. I think the next step is to check out the tube- do a beam pattern test before each mirror and if you have a laser power meter [ Russ calls it a lollypop ] do the same locations. You could do the same with a thick piece of acrylic [or fasten several 6mm pieces together?]. The heat is coming from the laser beam hitting the mirror housing somewhere,
