Title (EN) ELECTRODES FOR TRANSVERSELY EXCITED GAS LASERS
(FR) ELECTRODES DESTINEES A DES LASERS A GAZ EXCITES TRANSVERSALEMENT
Abstract:
(EN) An electrode for a transverse gas flow laser has a simplified profile which facilitates the fabrication and subsequent alignment of the electrodes within a laser cavity. Each electrode (10) is essentially comprised of an upper horizontally planar surface (12) having a surrounding radiused edge (14) of a given radius of curvature which is terminated by a surrounding vertical side wall (20). The termination of the radiused edge by the side wall acts to reduce the total electrode width, resulting in a reduction in required laser package size. A bottom surface (16) of the electrode may be provided with a mounting means (18), such as a plurality of tapped openings for bolting the electrode to an inner surface of the laser package.
(FR) Une électrode destinée à un laser à flux de gaz transversal possède un profil simplifié facilitant la fabrication et l'alignement subséquent des électrodes à l'intérieur de la cavité du laser. Chaque électrode (10) se compose essentiellement d'une surface (12) supérieure horizontalement plane comportant une arête (14) arrondie périphérique d'un rayon de courbure donné, terminée par une paroi (20) latérale verticale circonvoisine. La terminaison de l'arête arrondie par la paroi latérale contribue à réduire la largeur totale de l'électrode, ce qui a pour effet de réduire la taille du boîtier du laser. On peut pourvoir une surface (16) inférieure de l'électrode d'un moyen (18) de montage, tel qu'une pluralité d'orifices taraudés destinés à boulonner l'électrode à une surface interne du boîtier du laser.
