Abstract: A focused laser beam is directed at the wide side surface of a long, sealed, gas-filled, glass tube having a longitudinal axis and an elongated cross section. Repeated relative back and forth movement is introduced between the laser beam and the wide surface of the tube transverse to its longitudinal axis to heat and soften the tube along a cut line until the tube divides to form ends and collapses to seal the divided ends. Preferably, the tube is held in fixed position, while the laser beam is scanned across both of its wide side surfaces. The intensity and/or the velocity of the laser beam are modulated. After the tube divides along the cut line, the divided ends are annealed while still in the tube holder by defocusing the laser beam. In one embodiment, plural simultaneous cuts are made by directing a plurality of focused laser beams onto the tube at spaced intervals along its longitudinal axis.

Abstract: A self-luminous light source is disclosed having a light-permeable shell, a body disposed within the shell, defining a space between the shell and body, a member connecting the shell and body, radioactive gas disposed in the space, and a phosphor coating on at least one surface of the shell and body. The shell and body may be coaxial glass tubes defining an annular space of restricted width, connected to one another by annular end members.

Abstract: An elongated glass tube light source containing a luminophor and a radioactive gas is subdivided into a plurality of light sources by a plurality of laser beams directed at the tube at spaced points along the length of the tube. The laser beams are scanned back and forth transversely of the length of the tube to heat the tube and fuse the glass at each of the spaced points. The tube is rigidly supported on either side of each of the points to hold the tube stationary during the cutting operation. A single source of a continuous laser beam is divided into a plurality of beams by beam splitters. Mirrors direct the beams to the spaced points along the length of the tube and mirrors are oscillated to provide the desired scanning motion of the beams across the width of the tube.
