Abstract

Methods for the characterization and a numerical model of Er³⁺/Yb³⁺ codoped fibers for power fiber amplifiers and lasers are presented. The main goal of the developed model is to predict gain characteristics of an actual Er³⁺/Yb³⁺ fiber in the large-signal regime of operation. The numerical model is based on an iterative solution of the fiber propagation and the laser rate equations. The parameters of doping are obtained from the measurements of the saturation of absorption at a specific wavelength in the Er³⁺/Yb³⁺ doped fiber by fitting the measured curves of the absorption saturation using the developed theoretical model. For the parameters obtained, the numerical simulations of the gain are compared with the measured gain.
