Abstract

A fibre laser comprises a fibre light guide (3) having an active medium, a laser as pumping source (1) and a first pair of Bragg gratings (6, 8) forming a first resonator (4). The first pair of Bragg gratings (6, 8) resonates the pump laser (1) and there is provided a second pair of Bragg gratings (7, 9) resonating at the output wavelength of the fibre laser.
