La probl\u00e9matique du partenaire<\/strong><\/h5>\n\n\n\n

Situ\u00e9 \u00e0 Besan\u00e7on, l\u2019Institut FEMTO-ST<\/a> est un centre de recherche associ\u00e9 au CNRS. Il s\u2019int\u00e9resse entre autres, aux proc\u00e9d\u00e9s innovants de per\u00e7age et d\u00e9coupe laser pour un usinage rapide, pr\u00e9cis et efficace du verre<\/strong>. Ayant identifi\u00e9 les \u00abfaisceaux de Bessel\u00bb<\/strong> comme prometteurs pour le traitement du verre avec des lasers femtosecondes, l\u2019Institut recherchait une technologie de mise en forme de faisceau capable de produire des faisceaux de Bessel de haute qualit\u00e9 tout en g\u00e9rant les nombreuses contraintes<\/strong> qui accompagnent ce type de lasers.<\/p>\n\n\n\n

La solution CANUNDA-AXICON<\/strong><\/h5>\n\n\n\n

CANUNDA-AXICON est un axicon r\u00e9flectif<\/strong> fabriqu\u00e9 avec une extr\u00eame pr\u00e9cision. Cette pr\u00e9cision permet la g\u00e9n\u00e9ration de faisceaux de Bessel d\u2019une qualit\u00e9 remarquable. Sa nature r\u00e9flective lui permet de g\u00e9rer avec stabilit\u00e9<\/strong> des impulsions femtosecondes \u00e0 haute \u00e9nergie. Cela permet de percer des canaux avec un rapport de forme important<\/strong>, un profil d\u2019ablation homog\u00e8ne<\/strong> et un diam\u00e8tre allant jusqu\u2019\u00e0 l\u2019\u00e9chelle nanom\u00e9trique<\/strong>.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"
