摘要
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: S-4(3/2) -> I-4(5/2) (green), S-4(3/2) -> I-4(13/2) (red) and I-4(13/2) -> I-4(15/2) (IR)
