Laser control systems for additive manufacturing

Laser control systems and related methods for controlling arrays of lasers are disclosed. A laser control system may include a first controller configured to generate a trigger signal based on a position of a laser array, and a second controller configured to send a firing signal to one or more lasers of the laser array upon receiving the trigger signal. The one or more lasers may be selected based on a desired pattern of laser energy to be formed at a particular position of the laser array.

ENERGY DELIVERY OPTIMIZATION FOR LASER THICKNESS CONTROL OF FUSION GLASS SYSTEM AND METHODS

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.
