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.
