Just my two cents but would you not end up engraving on the mirror at this point being the beam is no changed and set to a focus I would only assume it will etch the mirror

Nope, the surface is too reflective, cutting or engraving relies on the material absorbing some of the radiated power at above it's yield point.

You did what !
Yes, the mirror coating would get damaged "if" I was working at the focal point. But I am work where it is half way to being focused. Also the mirror is silicon, so if the mirror surface failed it is likely that the mirror would crack or shatter.
