I decide to create a giant Mirror Shield that completely surrounds the Earth, or wherever we are.

If the Mirror Shield is left alone, the Superlaser will be ineffective against it, along with most energy weapons. However, as with all Mirror weapons and objects, it is not so effective against physical attacks (and is actually weak to such attacks), so a very powerful physical attack can break through and allow the Superlaser to destroy its target.
