Just out of my  curiosity, and with an ulterior motive, but considering how a high power laser would behave if it was to hit a mirror surface.  There are, as far as I know, two possibilities, it would either reflect, and in the process lose te coherence that concentrates the energy.  The other possibility, and here is where I don't have any experience with high power lasers, it might just see it as a surface to burn through.

Anyone have any laser experience to say which would be the most likely?  (Sci-Fi thing, thinking armor against other light weapons surrounding remotely controlled weapons which I have yet to make, not hand held, mounted in defensive structures.)
