Characteristics of ytterbium to erbium energy transfer in Yb:Er:phosphate glasses have been studied for a case when Nd phosphate glass laser is used as a pumping source. A theoretical model of the energy transfer was developed to reproduce the experimentally observed population dynamics of the Er3+ upper and lower laser levels. The results show that saturation and frequency hole burning of the inhomogeneously broadened Yb3+ absorption line are of primary importance in determining the dynamics and efficiency of the Yb3+ -Er3+ energy transfer under Nd laser pumping. The influence of other loss channels that have been identified in previous studies is found to be relatively small. The model also yields the lifetime of the frequency hole, as well as the effective rates of energy transfer between groups of Yb3+ and Er3+ ions in phosphate glasses
