    摘要： Various arrangements and methods are disclosed for forming one or more perforations on a substrate surface using a laser system, at least one rotating polygon mirror, and at least one other movable mirror. A rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate surface by incrementing (e.g., moving) a first mirror between a plurality of fixed (e.g., pointing) positions. A rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate using a first mirror that is maintained in a fixed (e.g., pointing) position. A first rotating polygon mirror and a second rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate surface, where the first and second polygon mirrors are used to define an extent of a given perforation in two dimensions on the substrate.

    摘要： A method is provided for operating a laser system. During an embodiment of this method, inert gas is directed against an object within a cavity of a collection device. An aperture is formed in the object by ablating the object with a laser beam that travels within the cavity and to the object. Byproducts of the ablation are removed from the cavity. During another embodiment of the method, inert gas is pooled against an object and a gas curtain is provided proximate a lens. The object is cut using a laser beam which travels from the lens, through the gas curtain and the pooled inert gas, to the object. Fumes and/or particulates produced by the formation are directed away from the laser beam.
