Vision correction and tracking systems may be used in laser machining systems and methods to improve the accuracy of the machining. 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. The vision correction and/or tracking systems may be used to provide scribe line alignment and uniformity based on detected parameters of the scribe lines and/or changes in the workpiece.

Laser machining systems and methods with vision correction and/or tracking

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.

Laser machining systems and methods with debris extraction

Laser machining systems and methods may use one or more moving laser scanning stages with force cancellation. The force cancellation is provided by moving masses linearly with equal and opposition motion. One or more of the masses may be a laser scanning stage. The laser machining systems 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.

Laser machining systems and methods with moving laser scanning stage(s) providing force cancellation

Multiple beamlet laser beam delivery systems and methods may be used in laser machining systems and methods to machine multiple regions on a workpiece simultaneously. One embodiment of a laser machining system and method may be used, for example, 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. The multiple beam delivery systems may be movable to scribe multiple lines simultaneously in the workpiece.
