abstract = "We present the determination of the energy transfer upconversion (ETU) coefficient for Nd:YAG via the z-scan technique, achieved by studying the irradiance dependence of the transmission of a pump laser tuned to the absorption peak around 808 nm. A spatially dependent two-level rate equation model has been utilized to predict the transmission dependence as a function of the sample's position in the z-scan experiment, with the ETU coefficient the only free parameter. Comparing experimental results with the model's output, the ETU coefficient for 1 at.\% Nd:YAG is determined to be 5.1 ± 0.4 ×10-17 cm3/s.",
