    The power doesn't exist anyway. The divergence (?) means that even after a few hundred miles, the point size of the laser is many times the radius of what it started out as. Even with our most powerful lasers which we regularly fire at a mirror on the moon (left on an Apollo mission) to test its distance, we can't 'see' the resultant reflection - instead we get a single photon response - ie. there's just no way with current tech we could do it. Even when we do get the power to do it, if we did fire an image with a single beam, we'd likely destroy any satellite that happened past - or, at best, we'd literally burn the atmosphere, creating a plasma front which would interfere with the beam, thereby still rendering any reflection invisible.
