Zusammenfassung:	The present disclosure relates to a machining apparatus for laser machining a workpiece, such as laser cutting. The apparatus includes a machining laser source for generating a machining laser beam; an illumination laser source having a power for generating an illumination laser beam having a spectral range; an outlet opening for the machining laser beam and the illumination laser beam; and a laser beam guiding device which is designed such that the machining laser beam and the illumination laser beam emerge coaxially through the outlet opening; wherein at least one element selected from the power of the illumination laser source and the spectral range of the illumination laser beam is selected such that the illumination by the illumination laser beam is brighter than a self-emission of the workpiece in a machining region during laser machining. Additionally, a method for laser machining a workpiece is also included in the present disclosure.
