Title
(EN) MATERIAL PROCESSING UTILIZING HIGH-FREQUENCY BEAM SHAPING
(FR) TRAITEMENT DE MATÉRIAU UTILISANT UNE MISE EN FORME DE FAISCEAU HAUTE FRÉQUENCE
Abstract
(EN)
In various embodiments, laser emissions are steered into different regions of an optical fiber, and/or into different optical fibers, in a temporal pattern such that an output has different spatial output profiles. The temporal pattern has a frequency sufficient such that a workpiece is processed by an effective output shape combining the different spatial output profiles.
(FR)
Dans divers modes de réalisation, les émissions laser sont dirigées dans différentes régions d'une fibre optique, et/ou dans différentes fibres optiques, selon un motif temporel de telle sorte qu'une sortie présente différents profils de sortie spatiaux. Le motif temporel a une fréquence suffisante pour qu'une pièce à usiner soit traitée par une forme de sortie efficace combinant les différents profils de sortie spatiaux.
