Definitions
- the structural member and the segments comprising the inner wall are made of a refractory ceramic, such as alumina or beryllia. However, other suitable materials can also be used.
- Terminating flanges 1 and tube 3 in Figure 1 define the gas chamber 11.
- the terminating flanges 1 are in electrical contact with electrodes 2 between which the discharge is propagated in the discharge chamber 12.
- Thermal insulation 4 is provided in order to raise the temperature of the metal segments 7 to the optimum value for lasing action.
- the tube 5 is supported co-axially with the thermal insulation 4 and individual rings 6 are disposed so as to form the appropriate structure with wells 13 in which to locate the metal. This creates the multiplicity of metal reservoirs disclosed in this invention.
- Such an insulating assembly is appropriate to a copper laser.
- the tube 3 defining the gas chamber is sealed against the terminating flanges 1 and 2 via O-rings (not shown) or some other suitable sealing technique.
- the whole assembly is connected to suitable power supplies, vacuum systems and cooling systems. These are all common in the art and do not form part of the invention.

Abstract
Un laser à vapeur de métal, destiné à être excité par une décharge électrique pulsée dont le volume est défini par une chambre (12) s'étendant entre deux électrodes (2) du laser, comporte plusieurs réservoirs (13) de métaux placés à intervalles réguliers à l'intérieur de la chambre sur toute sa longueur. Ces réservoirs sont destinés à empêcher le métal en fusion de s'amalgamer pour former une accumulation de métal étendu et à permettre le fonctionnement du laser dans des positions autres que des positions strictement horizontales. Les réservoirs de métaux sont de préférence définis par une série d'anneaux (6) en un matériau coaxial à l'axe du laser et disposé le long d'un tube (3, 8, 9) formant la chambre.
