Title (EN) COMPOSITE GRADED-INDEX FIBER MODE FIELD ADAPTOR FOR HIGH-ASPECT-RATIO CORE OPTICAL FIBERS
(FR) ADAPTATEUR DE CHAMP EN MODE FIBRE À GRADIENT D'INDICE COMPOSITE DESTINÉ À DES FIBRES OPTIQUES À CŒUR À RAPPORT DE FORME ÉLEVÉ
Abstract:
(EN) A fiber-based composite graded-index (GRIN) mode field adaptor configured to receive a circular Gaussian beam and to reformat the circular Gaussian beam into an elliptical Gaussian beam. Certain examples provide a fiber laser system including an input fiber configured to produce a circular Gaussian input beam, a semi-guiding high aspect ratio (SHARC) fiber, and the composite GRIN mode field adaptor coupled between the input fiber and the SHARC fiber, the composite GRIN mode field adaptor including a pair of GRIN lens fibers and being configured to receive the circular Gaussian input beam from the input fiber and to reformat the circular Gaussian input beam into an elliptical Gaussian beam to be coupled into the SHARC fiber.
(FR) La présente invention concerne un adaptateur de champ de mode à gradient d'indice (GRIN) composite à base de fibres configuré pour recevoir un faisceau gaussien circulaire et pour reformater le faisceau gaussien circulaire en un faisceau gaussien elliptique. Certains exemples concernent un système laser à fibre comprenant une fibre d'entrée configurée pour produire un faisceau d'entrée gaussien circulaire, une fibre à rapport d'aspect élevé semi-guidant (SHARC), et l'adaptateur de champ à mode GRIN composite couplé entre la fibre d'entrée et la fibre SHARC, l'adaptateur de champ à mode GRIN composite comprenant une paire de fibres de lentille GRIN et étant configuré pour recevoir le faisceau d'entrée gaussien circulaire en provenance de la fibre d'entrée et pour reformater le faisceau d'entrée gaussien circulaire en un faisceau gaussien elliptique à coupler dans la fibre SHARC.
