Title (EN) LASER BEAM SHAPING ELEMENT
(FR) ÉLÉMENT DE MISE EN FORME DE FAISCEAU LASER
Abstract:
(EN) The invention relates to an optical device and its use for generating a desired shape of the focus of a laser beam. By means of such a device changes in the beam spot geometry can be achieved in the focus area of the laser beam. The invention provides a focus-shaping element, wherein the focus-shaping element is refractive or reflective, comprising a segmented region with an array of polygonal lenslets for generating a polygonal main spot and at least one plane surface for generating at least one secondary spot.
(FR) L'invention concerne un dispositif optique et son utilisation pour générer une forme souhaitée du foyer d'un faisceau laser. Au moyen d'un tel dispositif, des changements de la géométrie du point de faisceau peuvent être obtenus dans la zone de focalisation du faisceau laser. L'invention concerne un élément de mise au point dans lequel l'élément de mise au point est réfractif ou réfléchissant, comprenant une région segmentée avec un réseau de petites lentilles polygonales pour générer un point principal polygonal et au moins une surface plane pour générer au moins un point secondaire.
