    摘要: Systems for scribing a workpiece incorporate a motorized beam expander to change a laser beam spot size incident on a workpiece. A system includes a frame, a laser coupled with the frame and generating an output to remove material from at least a portion of a workpiece, a beam expander positioned along a path of the laser output and having a motorized mechanism operable to vary a beam expansion ratio applied to the laser output, and at least one scanning device coupled with the frame and operable to control a position of the laser output, after expansion, on the workpiece. The motorized beam expander can be used to selectively vary the width of a laser beam supplied to a scanning device so as to selectively vary the size of the laser beam incident on the workpiece. Alternatively, a variable aperture can be used instead of a beam expander.

    摘要: In a system where scribe lines are formed by a series of partially-overlapping ablation spots, discontinuities can be detected by capturing an intensity of light generated during each instance of ablation for a respective spot. In any instance where the intensity of light given off falls below a desired threshold, such that the ablation spot might not sufficiently overlap any adjacent spot, the position of that instance can be captured such that another attempt at ablation can be carried out at that location.
