Abstract:
1. A method for processing first and second workpieces with a laser processing system, said laser processing system including a controller, a laser emitting a laser beam that propagates along a laser beam path and having laser optics, first and second motion stages for holding said first and second workpieces, a video assembly, and a gantry, said controller being operatively connected to said laser, laser optics, video assembly, gantry, and first and second motion stages, comprising: loading said first workpiece upon said first motion stage; aligning using said video assembly in cooperation with said controller to align said first workpiece in relation to said laser beam path; processing said first workpiece with said laser beam; loading said second workpiece upon said second motion stage; and while said first workpiece is aligned in relation to said laser beam path, using said video assembly in cooperation with said controller to align said second workpiece in relation to said laser beam path; wherein said operative connection of said controller with said laser, laser optics, video assembly, and first and second motion stages permits said controller, in cooperation with said gantry, to acquire and maintain said alignment between said second workpiece and said laser beam path during said processing of said first workpiece.
