CA 2724209

The invention relates to a device for joining and tapering fibres or cylindrical optical components, comprising a retaining device for holding the fibres or the optical components in the processing position, a laser radiation source (1) for emitting a laser beam and beam forming elements for guiding the laser beam to the processing site. At least a first beam forming element (4) is inserted into the beam path of the laser radiation source for producing a radiation having the form of an annulus and another second beam forming element (14) is provided for specifying the angle of incidence of the radiation having the form of an annulus onto the fibre(s) or the optical components in the processing position.

L'invention concerne un système pour réaliser un raccord et une transition progressive entre des fibres et/ou des composants optiques de préférence cylindriques, ce système comprenant un dispositif de maintien destiné à maintenir les fibres et/ou les composants optiques dans la position de traitement, une source de faisceau laser émettant un faisceau laser, ainsi que des éléments de mise en forme de faisceau servant à diriger le faisceau laser sur le lieu de traitement. Au moins un premier élément de mise en forme de faisceau est inséré dans la trajectoire du faisceau de la source de faisceau laser pour générer un rayonnement en anneau de cercle et un deuxième élément de mise en forme de faisceau est utilisé pour spécifier l'angle d'incidence du rayonnement en anneau de cercle sur la ou les fibres et/ou sur les composants optiques dans la position de traitement.
