Le partenaire<\/h5>\n\n\n\n

LASEA<\/strong><\/a>, entreprise belge, d\u00e9veloppe des syst\u00e8mes de micro-usinage par laser femtoseconde et poss\u00e8de une expertise dans de nombreux secteurs comme le m\u00e9dical, l\u2019industrie pharmaceutique, les produits de luxe, l\u2019industrie automobile ou encore l\u2019industrie \u00e9lectronique.<\/p>\n\n\n\n

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

La fabrication de puces microfluidiques<\/strong> est effectu\u00e9e par un assemblage de deux plaques polym\u00e8res, l\u2019une d\u2019entre elles comportant un motif de micro-canaux.
Ces v\u00e9ritables \u00ab laboratoires sur puces \u00bb permettent de reproduire le fonctionnement de syst\u00e8mes biologiques pour r\u00e9aliser des analyses, notamment m\u00e9dicales comme les tests PCR.<\/p>\n\n\n\n

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

L\u2019utilisation d\u2019un laser femtoseconde permet de graver les micro-canaux et de r\u00e9aliser une soudure solide et herm\u00e9tique entre les deux plaques de la puce microfluidique. Un enjeu important de ce proc\u00e9d\u00e9 est d\u2019augmenter la vitesse de soudage tout en am\u00e9liorant la qualit\u00e9<\/strong>, notamment gr\u00e2ce \u00e0 une mise en forme de faisceau homog\u00e8ne.<\/p>\n\n\n\n

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

CANUNDA-PULSE<\/a> est un module de mise en forme top-hat de haute qualit\u00e9. 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<\/strong>. Afin de garantir un fonctionnement m\u00eame face \u00e0 des instabilit\u00e9s<\/strong> de la source laser, la fonctionnalit\u00e9 filtrage de modes est impl\u00e9ment\u00e9e sur le module.<\/p>\n\n\n\n

\u201cNous d\u00e9veloppons des machines laser uniques qui permettent de r\u00e9aliser toutes les \u00e9tapes de fabrication des puces micro-fluidiques \u00e0 la suite. Avec la mise en forme du faisceau laser nous cherchions une am\u00e9lioration de la qualit\u00e9 de la soudure, ce qui a bien \u00e9t\u00e9 le cas. Nous avons en plus r\u00e9ussi \u00e0 augmenter la vitesse de soudure d\u2019un facteur 9 !<\/em>\u201d<\/p>\n\n\n\n
