Abstract: The invention relates to an optical fiber system for generating a side-emitting optical scattered laser radiation from a coupled optical laser radiation consisting of at least one side-emitting optical fiber with a fiber input and a fiber output, wherein the side-emitting optical fiber has at least one fiber core, a scattering layer surrounding the fiber core, and at least one cladding layer surrounding the scattering layer, wherein by the scattering layer, side-emitting scattered laser radiation is generated from the optical laser radiation coupled into the optical fiber, and wherein a coupling-side connecting section of the side-emitting optical fiber at the fiber input is received in a fiber connector and to produce a mechanical connection to the fiber connector. Particularly, at least the scattering layer and the at least one cladding layer are removed by stripping to suppress the side-emitting scattered laser radiation in the connecting section at the free end.

Abstract: A method is disclosed for joining two components (1, 2), a first component (I) and a second component (2), in the region of a joint zone by means of at least one laser beam. In a first phase, the first component (I) is melted, and a melt lens is formed in the first component (I) from the molten material (9). In a second phase, at least one pressure pulse is applied to the melt in the direction of the second component (2) until the melt lens is deflected into the joint gap as a result of the pressure pulse, bridges the joint gap, and comes into contact with the second component (2), and energy is transmitted to the second component (2) as a result of the melt lens coming into contact with the second component. A temperature curve results in the second component (2) as a result of the energy transmission such that the melting temperature is reached on the upper face of the second component (2), and a melt film is formed.
