Jc. Matin et al., ERBIUM-DOPED FIBER CHARACTERIZATION BY FLUORESCENCE DYNAMICS MEASUREMENT, IEEE journal of quantum electronics, 32(10), 1996, pp. 1727-1731
A technique for erbium-doped fiber characterization Is presented, Its
foundation lies in the study of the transversal and copropagating fluo
rescence time evolution when pumping is switched on and off. A model t
hat describes these phenomena is developed, and experimental results,
in good agreement with the model, are shown. The stimulated emission c
ross sections and an effective erbium-density distribution are determi
ned from the measurements.
