Abstract
A method of making a gaseous laser is disclosed using a thin-walled, ceramic tube such as alumina. Heat conducting members are assembled and aligned in a spaced-apart relationship within the tube. Coaxially aligned cylindrical shields are affixed to the heat-conducting members to control gas pumping within the tube. Bore-defining aperatures in the heat-conducting members, or in sputter-resistant discs affixed to the heat-conducting members, are aligned by a mandrel under tension at which time the parts are permanently bonded within the tube.
Claims14
A method of fabricating a gaseous laser discharge tube comprising:
- assemblying a plurality of spaced-apart heat-conducting members, each having a discharge defining central aperture generally aligned with the tube axis, within and in contact with an electrically-insulating tube;
- tensioning a mandrel provided through the central apertures to bring the central apertures into exact alignment;
- and
- permanently securing the heat-conducting members to the electrically-insulating tube.
