    How works a beam?

    Yes, that's something i found out searching around. So, that's going to be my first laser. :) And of course a 'real' 5mw, not an 'ebay' 5mw.

    How works a beam?

    Maybe this isn't the question to start with on this forum, but i have a 'fight' about this, and i know for sure i'm right :P. You can see the beam of a laser (from +/- 5mw) in the dark, without smoke or something, right (please confirm)? Now, how does that work? Are there little dust 'things'...
