I use it to play with some of my smaller laser hosts, I have about 12 beam expanders of different types, I just like to collect them, occasionally use them.
6000 ft? Wow. Nice! Just happened to see this and was thinking of doing something very similar! Used to do this with a 1.8W near IR diode laser.Thanks, it put a nice bright green spot on a 6,000 foot high cloud base tonight Only thing is, those darn wings! I can't seem to get rid of them unless I mask the beam output using this kind of beam expander.
