Abstract
L'invention concerne les lasers à gaz. Le laser à gaz comprend le boîtier 1 renfermant deux électrodes 2, 3. L'électrode 2 est sectionnée, et à chaque section 4 est connectée une résistance ballast 5. L'électrode 3 est fixée au boîtier avec possibilité de modifier l'écartement entre les électrodes dans le sens du flux de mélange de gaz. Entre les électrodes 2 et 3 existe la zone 12 où est créé l'effet laser et qui est traversée par le mélange de gaz. Application dans divers domaines techniques, notamment au soudage, découpage et traitement thermique de divers matériaux.
