Are green lasers actually visible along their entire lengths? I used to have a green laser pointer and it wasn't. It would make sense that as green is a more visible wavelength of light it would be easier to see a green laser with less dust/fog, but wouldn't it have to be pretty massively powerful to actually be visible along it's whole length?
The internet is being unhelpful, and I assume someone here actually has one.
