Abstract
An analytical model is developed to study the influence of the Auger upconv ersion process on the thermal loading under lasing and nonlasing conditions . With the developed model, Auger upconversion rates can be determined by c omparing theoretical calculations with experimental results for the ratio o f the thermal loading under lasing and nonlasing conditions. The upconversi on rates obtained with the present method are compared with the results mea sured from the fluorescence decay experiment.
