Abstract

We have developed a model of Er/Yb co-doped glasses taking into account upconversion and concentration quenching. We show in this paper that co-doping with Yb does not affect the maximum gain attainable at very high pump power, but significantly enhances the pump efficiency at moderate pump levels.
