Abstract:
A method for filamentation of a dielectric workpiece has a workpiece with a thickness between 0.5 and 20 mm is provided. The workpiece has boundary surfaces delimiting the workpiece. The thickness of the workpiece varies spatially and/or at least one of the boundary surfaces delimiting the workpiece has at least one curvature with a radius of curvature between 0.1 μm and 10 m. The dielectric workpiece can have a specially formed edge.
