ABSTRACT:
The end of an optical fibre is held in alignment with an injection laser by securing the fibre to an elongate support member whose end nearer the injection laser is then laser beam welded to a pair of slide members that have previously been secured by laser beam welding to leave a precisely dimensioned small gap between the support and slide members. The smallness of the gap minimises displacement of the fibre during the welding process. The end of the support member remote from the injection laser is secured by laser beam welding to a plastically deformable saddle.
