Abstract
Apparatuses and methods are described for controlling the thickness of glass during glass sheet production. The apparatuses and methods employ a laser beam to heat a particular portion of the molten glass. In some examples, a laser beam control system controls the laser beam to generate a more consistent glass thickness across the glass sheet. In some examples, the laser beam control system multiplexes the laser beam to heat various portions of the glass, for example, simultaneously.
