Abstract

An apparatus for cutting a material having a thickness, T, defined by the distance between a first surface and a second surface of the material. The apparatus comprises an energy source for providing a beam of energy, and directing mirrors for directing the beam of energy from the energy source to a first focal point between the first and second surfaces of the material, and to a second focal point between the first and second surfaces of the material. The first and second focal points are spaced apart from each other by a distance sufficient to cut through the entire thickness of the material.
