ABSTRACT:
A bore tube free end support structure is positioned between an outer cylindrical envelope and an inner capillary bore tube of a laser. The support structure has outer and inner pluralities of circumferentially-spaced spring fingers integrally connected to and extending from respective outer and inner peripheries of a solid annular disc-like middle portion thereof. The outer spring fingers are alternately bent in opposite directions. The outer end of each outer spring finger defines a pair of pointed corners adapted to dig into the inside surface of the glass outer envelope of the laser, so as to anchor the support structure firmly in position with respect thereto. The inner spring fingers all extend in the same direction and each is arcuate-shaped in a longitudinal section therethrough. The inner spring fingers are thus adapted to engage the outside surface of the bore tube in a frictional sliding contacting relationship which allows longitudinal shifting but restrains transverse shifting of the bore tube relative to the outer envelope and a central axis of the laser.
