    摘要: A layer (22) on a substrate (24) is laser annealed by pulses in a plurality of laser beams (14A – 14D) formed into a uniform line beam (20). The laser beams (14A – 14D) are partitioned into a first set of beams (14A,14D) and a second set of beams (14B,14C). The second set of beams (14B,14C) is incident onto the layer (22) from a smaller range of angles than all of the beams (14A – 14D) combined. Pulses in the beams (14A – 14D) are synchronized such that pulses in the first set of beams (14A,14D) are incident on the layer (22) before pulses in the second set of beams (14B,14C). Pulses in the first set of beams (14A,14D) melt the layer and pulses in the second set of beams (14B,14C) sustain melting.

    摘要: Methods, systems, devices, and substrates are described. In some examples, an apparatus may include optical components configured to adjust an input to a laser cutting optic for modifying a substrate (e.g., an optically transmissive substrate). In some examples, the optical components may include a beam deflector, a first optic configured to output a first laser beam with a first beam width, and a second optic configured to output a second laser beam with a second beam width. In some examples, the beam deflector may modify an optical path of a pulsed laser (e.g., through the first optic or through the second optic), which may result in an input to the laser cutting optic having a beam width corresponding to the first optic or the second optic. The different input beam widths may modify a line focus intensity of an output of the laser cutting optic when modifying the substrate.

    摘要: Eine Anordnung zur Lasermaterialbearbeitung weist wenigstens eine Laserstrahlquelle (5), eine Strahlaufteilungseinrichtung (6), eine Modulationseinrichtung mit mehreren akusto-optischen Modulatoren (4) und eine dynamische Strahlablenkeinrichtung (9) auf. Durch die Strahlaufteilungseinrichtung (6) wird ein kollimierter Laserstrahl (10) zweidimensional in mehrere Teilstrahlen (1) aufgeteilt, die in wenigstens einer ersten Dimension nicht parallel zueinander verlaufen. Zwischen der Strahlaufteilungseinrichtung (6) und der Modulationseinrichtung ist eine optische Anordnung zur Parallelisierung der Teilstrahlen (1) in der ersten Dimension angeordnet. Diese optische Anordnung weist eine Anordnung mehrerer Prismen (12) auf, die so ausgebildet und angeordnet sind, dass die Teilstrahlen (1) beim Durchgang durch diese Prismen (12) durch jeweils zweifache Brechung in der ersten Dimension parallel zueinander ausgerichtet werden. Dadurch bleibt die Kollimierung der Teilstrahlen (1) in den akusto- optischen Modulatoren (4) erhalten, so dass die Modulation in den akusto-optischen Modulatoren (4) mit maximaler Effizienz erfolgen kann. Die Anordnung lässt sich dadurch auch in kompakterer Bauweise realisieren.
