CA 2189568

An optical fibre distributed feedback laser comprises an amplifying optical fibre (50) operable to provide optical gain at a lasing wavelength, in which a diffraction grating (30) is disposed on at least a portion of the amplifying optical fibre to provide distributed optical feedback for sustaining lasing action at the lasing wavelength.

Un laser à fibre optique et à réflectivité répartie comprend une fibre optique d'amplification (50) servant à produire un gain optique à une longueur d'onde laser et sur au moins une partie de laquelle se trouve un réseau de diffraction (30) permettant d'obtenir une répartition de la réflectivité optique, afin d'entretenir l'action laser à la longueur d'onde laser.
