Le partenaire <\/h2>\n\n\n\n

ALPhANOV <\/a>est un centre technologique optique fran\u00e7ais poss\u00e9dant une expertise dans les proc\u00e9d\u00e9s laser et le micro-usinage. Son objectif est de stimuler l\u2019innovation au travers de collaboration entre la recherche et l\u2019industrie. Il \u00e9tudie, d\u00e9veloppe et caract\u00e9rise, entre autres proc\u00e9d\u00e9s, la fonctionnalisation de surface.<\/p>\n\n\n\n

L\u2019application<\/h5>\n\n\n\n

La fonctionnalisation<\/strong> ou texturation de surface <\/strong>par laser permet de donner de nouvelles propri\u00e9t\u00e9s \u00e0 la surface d\u2019un mat\u00e9riau en g\u00e9n\u00e9rant des micro ou nano structures avec un faisceau laser. Par exemple, il est possible de donner \u00e0 une surface des propri\u00e9t\u00e9s hydrophobes, hydrophiles, antibact\u00e9riennes ou encore de pi\u00e8ge \u00e0 lumi\u00e8re.<\/p>\n\n\n\n

La probl\u00e9matique<\/h5>\n\n\n\n

ALPhANOV souhaite ouvrir la voie \u00e0 une utilisation industrielle du proc\u00e9d\u00e9 de g\u00e9n\u00e9ration de LIPSS (Laser Induced Periodic Surface Structures), qui permet notamment de conf\u00e9rer des propri\u00e9t\u00e9s de pi\u00e8ge \u00e0 lumi\u00e8re \u00e0 la surface usin\u00e9e. Cette industrialisation passe par l\u2019utilisation d\u2019une technologie de mise en forme de faisceau compatible avec des lasers femtosecondes permettant d\u2019optimiser la d\u00e9position d\u2019\u00e9nergie.<\/p>\n\n\n\n

La solution CANUNDA-PULSE<\/h5>\n\n\n\n

CANUNDA-PULSE est un module de mise en forme top-hat de haute qualit\u00e9.<\/strong> De conception enti\u00e8rement r\u00e9flective gr\u00e2ce \u00e0 la technologie MPLC, il est sp\u00e9cifiquement con\u00e7u pour r\u00e9sister aux impulsions laser femtosecondes hautement \u00e9nerg\u00e9tiques<\/strong> avec une remarquable stabilit\u00e9. Afin de garantir un fonctionnement m\u00eame face \u00e0 des instabilit\u00e9s de la source laser, la fonctionnalit\u00e9 filtrage de modes<\/strong> est impl\u00e9ment\u00e9e sur le module.<\/p>\n\n\n\n

\u201c La mise en place de strat\u00e9gies de \u00ab beam shaping \u00bb permettant l\u2019utilisation de toute la puissance disponible avec les sources laser femtoseconde de derni\u00e8re g\u00e9n\u00e9ration (centaines de W) ouvre de grosses possibilit\u00e9s pour l\u2019exploitation dans les domaines industriels de la technologie MPLC. \u201d<\/em><\/p>\n\n\n\n

Int\u00e9gration industrielle du module CANUNDA-PULSE<\/h5>\n\n\n\n

CANUNDA-PULSE a \u00e9t\u00e9 install\u00e9 sur une station de micro-usinage laser femtoseconde dans le but de g\u00e9n\u00e9rer des structures de surface sur de l\u2019acier inoxydable 316L<\/strong>, conf\u00e9rant ainsi \u00e0 la surface une fonction de pi\u00e8ge \u00e0 lumi\u00e8re et donnant \u00e0 l\u2019\u00e9chantillon une coloration noire.<\/p>\n\n\n\n
