Abstract:
Method and apparatus for laser scoring a sheet material. An elongated laser beam having S-mode intensity profile in the width direction and a flat-top-mode profile in the length direction is used to achieve high precision scoring. The invention can be used for scoring large-size glass substrates for LCD displays.
