Abstract
A method for manufacturing an optical fibre, in which a preform is inserted into a furnace, the preform is drawn via an outlet of the furnace, and at least one laser beam is applied to a working zone of the drawn preform, each laser beam being power-modulated according to a modulation frequency. A device for manufacturing an optical fibre is also provided.
