Les simulations de l\u2019\u00e9quipe de recherche ont montr\u00e9 l\u2019importance d\u2019homog\u00e9n\u00e9it\u00e9 du champ \u00e9lectrique qu\u2019il a \u00e9t\u00e9 n\u00e9cessaire de traduire en termes de conception et r\u00e9alisation m\u00e9canique.<\/p>\n\n\n

D\u00e9veloppement d\u2019un laser puls\u00e9 nanoseconde dans le cadre d\u2019une\ncollaboration avec le CERN dans le but de produire de l\u2019anti hydrog\u00e8ne. Il s\u2019agit d\u2019un laser\noriginal sans \u00e9quivalent commercial g\u00e9n\u00e9rant des impulsions de 40 ns \u00e0 10Hz, intenses\n(quelques mJ) et spectralement fines (environ 50MHz pour compatibilit\u00e9 avec l\u2019effet Doppler\ndu second ordre des transitions de l\u2019hydrog\u00e8ne ou de positronium). La longueur d\u2019onde est\naccordable entre 720 et 730 nm (transition 2s\u2192nl de l\u2019an hydrog\u00e8ne). En effet une fois doubl\u00e9\nen fr\u00e9quence entre 360\u2010365nm il permettra l\u2019excitation \u00e0 deux photons sans effet Doppler (du\npremier ordre) du Positronium via la transition 1s\u2192nl. Les longueurs d\u2019ondes sont contr\u00f4l\u00e9es\npar un lambdam\u00e8tre ext\u00e9rieur et par un asservissement num\u00e9rique se calant sur un maximum\nde transmission de la cavit\u00e9 laser.<\/p>\n\n\n
