英文摘要	Optical arrangements for processing a workpiece include a fiber laser arrangement for emitting laser radiation, a fiber arrangement directly coupled to the fiber laser arrangement and configured to guide the laser radiation in a direction to the workpiece to be processed, the fiber arrangement including a transport fiber having a fiber core and at least one fiber cladding surrounding the fiber core, and at least one coupling device for coupling a portion of the laser radiation guided in the fiber arrangement into at least one fiber cladding of the transport fiber. The coupling device has a spectral bandwidth of at least the same magnitude as a spectral bandwidth of the laser radiation. The fiber laser arrangement is configured to change a beam profile of the guided laser radiation to shift the spectral bandwidth of the laser radiation relative to the spectral bandwidth of the coupling device.
