Abstract

1,247,868. Lasers. RANK ORGANISATION Ltd. 26 March, 1969 [3 April, 1968], No. 15948/68. Heading H1C. To facilitate replacement in a laser of a gas laser tube without disturbing the optical alignment, the tube 1 is mounted on V-blocks 9, 10 between external reflectors 11, 12, and each tube intended for use in the arrangement has its wall formed accurately with respect to its internal bore at least over the area of contact with the blocks. Similar manufacturing uniformity is applied to the thickness of brewster end windows 6. The wall of the laser tube may be ground to the required dimension, or a pair of rings with accurately formed outer diameters may be fitted round the tube, the rings being located within a cylindrical bore. The tube incorporates discharge electrodes 2, 3 and may contain helium-neon gas mixture.
