Abstract: An apparatus includes a beam splitter and a plurality of mirrors. The beam splitter is positioned to receive a laser beam from a source and split the received laser beam to a first plurality of split laser beams and a second plurality of split laser beams. The plurality of mirrors is configured to direct the first plurality of split laser beams and further configured to direct the second plurality of split laser beams. The first plurality of split laser beams is directed by the plurality of mirrors is configured to cut a glass substrate. The second plurality of split laser beams is directed by the plurality of mirrors is configured to shape the glass substrate.

Abstract: A method includes projecting energy onto an annular edge of a glass substrate. The annular edge includes a first roughness. The first roughness is reduced to a second roughness with the energy. The energy reduces the first roughness without changing a roundness of the annular edge of the glass substrate.
