  • Laser machining systems and methods with debris extraction
    Patent number: 8633420
    Abstract: Laser machining systems and methods may include debris removal systems to remove debris generated by the machining process and/or outgassing or filtration systems to remove harmful gases and filter and recycle air within the system. The laser machining systems and methods may be used to scribe one or more lines in large flat workpieces such as solar panels. In particular, laser machining systems and methods may be used to scribe lines in thin film photovoltaic (PV) solar panels with accuracy, high speed and reduced cost.
    Type: Grant

  • LASER MACHINING AND SCRIBING SYSTEMS AND METHODS
    Publication number: 20110132885
    Abstract: A laser machining system may include an opposite side camera to provide workpiece alignment from an opposite side of the system (i.e., the side opposite the laser machining process). The opposite side camera may be used with an air bearing positioning stage, and a portion of the stage and/or the opposite side camera may be moved to allow the opposite side camera to image a feature on the workpiece to be aligned. The opposite side alignment may be used with back side scribing and/or dual side scribing of a workpiece with alignment from one or both sides of the workpiece. Laser machining systems and methods may also be used to provide quasi-stealth scribing and multi-beam scribing.
