ABSTRACT:
An optical fiber (F) and a laser (L) are fixed on the top faces of two bases (EF, EL) which also have two facing vertical faces. A spring (4) presses these two faces against each other so as to create thrust friction. The thrust force is initially moderate in order to enable the relative vertical and transverse positions (GV, GT) of the two bases to be adjusted smoothly, after which the force is increased progressively in order to prevent relative displacement taking place while the two bases are being welded together by means of a YAG laser. The invention is particularly applicable to making optical transmission heads usable in optical fiber telecommuncations systems.
