Abstract

L'invention porte sur un laser à gaz à fente doté d'un résonateur instable à branche négative d'instabilité et à pompage haute fréquence. Ce laser à gaz comprend des électrodes métalliques (6, 7) étendues qui forment un intervalle (5) de décharge et sur la surface desquelles, côté décharge, sont formées des cavités de type gorges (9) qui s'étendent de façon orthogonale par rapport à l'axe optique du laser. De par cette configuration, les électrodes forment dans le résonateur une combinaison de guide d'ondes dans lequel un rayonnement se propage le long de l'axe du laser et d'un espace libre pour la propagation du rayonnement dans le sens orthogonal par rapport à l'axe du laser. Les gorges (9) forment ainsi un système de filtres spatiaux permettant la sélection du mode de base du rayonnement laser, ce qui entraîne également une réduction de la divergence du rayon laser. Sur tous les éléments fonctionnels du laser, excepté le miroir du résonateur et la fenêtre de sortie, est disposé un revêtement de type film en aluminium pur dont l'épaisseur est comprise entre 1 et 5 νm. Le film obtenu selon ce type de déposition par projection exerce une influence sur la composition du milieu gazeux du laser en augmentant la durée de vie du dispositif.
