Verfahren und Anordnung zum Strukturieren einer lichtleitenden Faser entlang deren Laengsachse (longitudinale Strukturierung) basierend auf der nicht-linearen Absorption von Laserstrahlung

DE 102006046313 B3 UPAB: 20080331 NOVELTY - A structuring method in which along the z-optic axis a laser beam is directed onto the surface of a fiber (3), the Rayleigh length (P) of the optical system (1a,2) consisting of the laser (1a) and the focusing optics (2) is adjusted so that the minimum of the correlation (z'(z)) between the beam waste position (z') of the surface (3a) of the fiber (3) facing the optical system (1a,2) and the beam waste position (z) of the fiber incident on this system, falls in this region of the fiber core. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an arrangement with laser and focusing optics. USE - For structuring fiber optics in optical telecommunications method. ADVANTAGE - Makes available a beam shaping and positioning procedure for longitudinal structure for fiber optic line
