This paper reports the dynamic characteristics of sequential energy transfer up-conversion processes in Yb 3+ /Er 3+ :SrMoO 4 crystal. A general method based on the emission intensity has been developed to calculate the nonradiative decay rate. A new macroscopic theory has been developed to calculate the energy transfer parameters based on the crystal structure. According to both new calculating methods, the spectral parameters of Yb 3+ /Er 3+ :SrMoO 4 crystal were calculated, such as up-conversion luminescent quantum efficiencies and threshold pump powers. Both calculating methods may be applied to calculate the spectral parameters of the laser crystal materials.
