Laser thickness control of fusion glass

A method of manufacturing a system for providing laser thickness control, the method comprising:

• providing a glass forming body configured to enable molten glass to flow along at least one surface of the glass forming body to form a glass ribbon, and wherein the molten glass defines a first face with a width extending from a first edge to a second edge;
• providing a first laser module that is configured to generate a first laser beam that is scanned at least partially along the width of the first face within a scan angle range so as to apply heat to aid in thickness control of the glass ribbon;
• and
• positioning the first laser module so that the first laser module directs the first laser beam towards the first face,
• wherein the first face defines a normal direction that is normal to the first face, and wherein a central facing direction of the scan angle range for the first laser beam strikes the first face at a central strike angle that is not normal to the first face.
