Chapitre III Amélioration <strong>de</strong> la superrésolution <strong>de</strong>s faisceaux lasers par <strong>de</strong>s éléments optiques <strong>de</strong> phase Comme <strong>de</strong>rnier point, on note qu'il faut forcer le laser pour qu'il puisse osciller en mo<strong>de</strong> fondamentale en forme <strong>de</strong> faisceau TEMp0, cela est possible par l'insertion soit d'un élément <strong>de</strong> phase [23-29], soit d'un élément absorbant [29-30] dont sa géométrie est en concordance avec les zéros <strong>de</strong>s polynômes <strong>de</strong> Laguerre, on note aussi que l'utilisation <strong>de</strong>s éléments <strong>de</strong> phase est plus efficace pour la sélection <strong>de</strong>s mo<strong>de</strong>s d'ordres supérieurs qu'à l'utilisation <strong>de</strong>s éléments absorbant, car ces <strong>de</strong>rniers introduisent <strong>de</strong>s pertes au laser. 74
