  "textContent": "A laser system for generating a line beam includes a plurality of laser sources to generate a plurality of laser beams, light pipes arranged to transmit and homogenize the laser beams to transform the laser beams into homogenized laser beams, and relay optics to direct and image the homogenized laser beams from the light pipes onto a common focal plane, whereby the homogenized laser beams form a line beam that, in the common focal plane, includes images of the output ends of the light pipes stitched together along a line-axis of the line beam. Adjacent images in the common focal plane are non-overlapping while having overlapping projections onto the line-axis or onto another axis that is orthogonal to a transport direction of a workpiece through the line beam. The overlapping projections average defocusing-induced seam-effects over a larger region and thus lessen their impact on the laser irradiation process.",
