1. An optical mirror, comprising:
a base layer;
a binder layer, overlying and energetically bonded to the base layer, comprising aluminum metal;
a reflective layer, overlying the binder layer, comprising aluminum metal;
a protective layer, overlying the reflective layer, comprising silicon dioxide; and
