Huh, I just discovered that my homemade 635nm pointer will pop unsharpied blue balloons out to at least two feet. It takes a while though, close to minute at two feet. It's interesting as you can see patterns in the reflected light as the rubber slowly melts prior to popping. I'm using one of those Meredith brass lens assemblies that can be focused. The focus is critical. I'm surprised it's able to pop them. Any idea if there's a way to figure what the power level of the laser is? I don't have a laser power meter so I've often wondered. I'm guessing it's in the 20-30 mW range. Weeee.

It would really depend on how focused the beam is. I've popped a balloon with a 24mW laser without any external lenses, just the collimated beam. Thus a 10mW laser should be able to pop a balloon if the beam is focused properly. It's likely yours is outputting more then 5mW, but how much more is hard to say. _________________ Cheers, Sean.
