Deformable mirror corrects errors

Very high power is needed to cut or weld using a laser beam. But this creates its own problem: the beam’s energy deforms the mirrors that are focusing it to a point. When this happens, the beam expands and loses intensity. A new type of mirror can deform itself so as to correct this unwanted deformation.
