Abstract

In our work, we develop a numerical model for studding the variation of phenomenological and optical parameters in an Er⁺³ system of 6 excited levels that is subject to a lasing condition. The model is using a four order Runge- Kutta method to solve a system of eight time-dependent variables. The simulations, based on the change of pumping wavelength, prove that the highest efficiency is reached for a 970 nm pump wavelength, concordant with the existing literature results. Different processes, including: three ion-ion up-conversion processes, two pumping processes and the inherent spontaneous transition, are considered.
