    This paper models the mechanism of upconversion and energy transfer between Er and Yb ions in diode-pumped Er, Yb : CaYAlO4 crystal. Rate equations are used for modeling and are solved numerically for the populations of different levels as a function of time. Many input parameters are measured experimentally and the rest of the parameters are predicted from the model. Population inversion is studied for these transitions in Er : [MATH
