    摘要： In a method for laser material processing a workpiece (2), in particular for laser cutting or laser welding, wherein by means of a laser beam (1) at least a part of the workpiece (2) is melted and/or vaporized and an irradiation front (3) is formed by adding a relative movement between the laser beam (1) and workpiece (2), according to the invention the surface structure of the irradiation front (3) is adjusted in accordance with a desired processing result. The surface structure of the irradiation front (3) can be adjusted, for example, by suitably selecting beam properties of the laser beam (1), in particular the polarization and/or beam profile.

    摘要： The invention relates to a laser cutting machine (1) for cutting a workpiece (2a) with a first thickness (D1) using a first machining laser beam (3a) with a first laser beam characteristic and for cutting a workpiece (2b) with a different second thickness (D2) using at least one second machining laser beam (3b) with a different second laser beam characteristic, having: a laser source (4), in particular a solid-state laser, for generating a raw laser beam (5) with a laser wavelength of less than 4 µm, a machining head (6), a device (7) which forms the machining laser beams (3a, 3b) with the first and with the second laser beam characteristics from the raw laser beam (5), and a controller (8) which controls the device (7) dependent on the thickness (D1, D2) of the workpiece (2a, 2b) to be cut. The invention also relates to a method for cutting workpieces (2a, 2b) of different thicknesses (D1, D2) using a machining laser beam (3a, 3b), wherein workpieces (2a) with a first thickness (D1) are machined using a first machining laser beam (3a) with a first laser beam characteristic and alternatively workpieces (2b) with a different thickness (D2) are machined using at least one second machining laser beam (3b) with a different second laser beam characteristic.
