If you pointed a powerful laser (like the ones the military are using to take down missiles) at a mirror would it burn through the mirror or bounce off it?

Well, even a really great mirror isn't 100% reflective, so it will always absorb some of the light.  If you pump strong enough, yes, you'll start to heat up the mirror faster than it can dissipate the heat and eventually it will melt. 

 Another thing to consider is that the reflectivity of a surface depends heavily on the wavelength of light.  A mirror that might be reflective to visible light, say 99% reflective, might only be 5% reflective to infrared light.  So if you were trying to build an anti-missile laser or a laser-proof missile hull, for example, you'd want to take that into account.
