Abstract

L'invention concerne un laser compact à impulsions gazeuses dont la cellule à décharges sectionnée coaxiale comporte un intervalle entre le tube de décharges (1) et les tubes d'anodes (15) dont l'épaisseur est supérieure à celle de l'épaisseur de la paroi du tube d'anode. Le tube d'anode est inséré dans le dispositif de compression magnétique des impulsions (3) de manière à assurer la liaison induction / capacité avec des réacteurs saturables (19). Deux capacités de ballast (4) sont disposées coaxiales avec la cellule à décharges, symétriquement par rapport au dispositif de compression magnétique de l'impulsion; elles sont montées étanches sur le corps du dispositif de compression magnétique de l'impulsion (27). Le dispositif de compression magnétique, réalisé selon un schéma à articulations multiples sur des réacteurs saturables à anneaux de ferrite, présente un schéma parallèle de branchement de lignes électriques longues (23, 25). Le nombre de lignes est pair, et chaque ligne de compression magnétique utilise un réacteur saturable supplémentaire dans une première articulation, le réacteur saturable supplémentaire (29) étant branché en parallèle sur le corps du dispositif de compression magnétique, ainsi qu'un condensateur d'affûtage (28).
