Abstract :
The power rising of an actively Q-switched erbium-doped fibre laser by using two coupled cavities with amplifying fibres in an interferometer configuration is reported. This study shows that the pulse peak power obtained is 1.7 higher than in a case of a unique laser. This concept brings some novel perspectives for scaling the output peak power of singlemode Q-switched fibre lasers.
