FAST METHOD FOR OBTAINING ERBIUM-DOPED FIBER INTRINSIC PARAMETERS

The authors present a fast, simple and nondestructive method to charac terise rare-earth-doped fibres (REDF). They measure the response of th e fibre to a step-like pulse excitation and obtain, from a single meas urement, the intrinsic saturation power, the excited-stale lifetime an d the linear absorption coefficient, which are fundamental for a compl ete modelling of REDF devices. They demonstrate the method using diffe rent erbium-doped fibres (EDF).
