Abstract
L'invention concerne un laser à cathode creuse, à auto-confinement. Il comporte une cathode cylindrique enfermée dans une enveloppe allongée comprenant deux sections d'extrémités. Deux anodes, une dans chaque section d'extrémité, amènent l'énergie électrique qui excite la matière dans l'enveloppe tout en développant un effet de cataphorèse empêchant la matière excitée de venir en contact avec les fenêtres de transmission disposées en bout de chaque section d'extrémité. L'invention s'applique notamment à des lasers à l'hélium-cadmium.
