A Method to Calculate the Emission Cross Section of Rare-Earth Ions
A method to calculate the emission cross section of rare earth ions was introduced based on the combination of the McCumber theory with Judd Oflet theory. The method is very simple and only needs to measure the absorption spectra. The emission cross sections of Tm 3+ , Yb 3+ and Er 3+ ions from the first excited state to the ground state were calculated in this way. The results indicated that the method is practical.
