Abstract

Light guide fibres made of quartz glass may be joined by irradiation of parts of the fibres using focused carbon dioxide laser beams. At least a section of the outer surfaces of parts of the light guide fibres to be connected is irradiated with a focused carbon dioxide laser beam of a wavelength which is absorbed by the fibres. During the fusion process short sections of the light guide fibres are placed one upon another in an axial direction. Since the light guide fibre (11) has a small diameter (d), heat convection is produced uniformly in the entire terminal face of the fibre.
