Abstract: front page image
(EN)A gaseous laser includes a gas discharge tube (12) made of a comparatively thin-walled ceramic tube (26). Heat from the discharge is transmitted to the exterior tube by conduction through thin-walled, cupshaped members (50) which are assembled and aligned in a spaced-apart relationship within the tube (26). Bore-defining apertures (46) in the heat-conducting members (50), or in sputter-resistant discs (48) affixed to the heat-conducting members (50), are aligned by a mandrel (74) under tension at which time the parts are permanently bonded within the tube (26). Also coaxially affixed to the cup-members (50) are cylindrical shields (56) which control gas pumping within the tube (26). Gas return holes (54) are provided in the cup-members (50).
(FR)Un laser a gaz comprend un tube a decharge gazeuse (12) compose d'un tube en ceramique a paroi relativement mince (26). La chaleur provenant de la decharge est transmise au tube exterieur par conduction au travers d'organes a paroi mince et en forme de cuvettes (50) qui sont assembles et alignes a l'interieur du tube (26) mais ecartes les uns des autres. Des ouvertures definissant un alesage (46) dans les organes conduisant la chaleur (50), ou dans les disques resistant au crepitement (48) fixes aux organes conduisant la chaleur (50), sont alignes par un mandrin (74) sous tension et simultanement les parties sont soudees a l'interieur du tube (26) de maniere permanente. Fixes de maniere coaxiale aux organes en forme de cuvettes (50) se trouvent aussi des ecrans cylindriques (56) qui commandent le pompage de gaz a l'interieur du tube (26). Des trous de retour de gaz (54) sont amenages dans les organes en forme de cuvettes (50).
