This development works on the primary mirrors which now has the capability to correct mirror reflection changes due to a megawatt laser impact.
So after the laser hit, there are built in on the surface of the mirror are what sounds like micromechanical actuators with the design to re engineer the optics in real time to recreate the same laser interaction but testable at lower levels.
