Dependence Of The Yb3+ Emission Cross Section And Lifetime On Temperature And Concentration In Yttrium Aluminum Garnet
Measurements are reported of the speetroscopic properties (absorption and emission spectra, stimulated-emission cross section, and radiative lifetime) of (YbxY1-x)3Al5O12 for nominal x values of 0.025, 0.05, 0.1, 0.2 and 0.3 at temperatures of 15-300 K. The emission cross sections of Yb:YAG with different Yb3+ concentrations were determined by use of the Füchtbauer-Ladenburg formula and the reciprocity method. At low temperatures, the product (στ) of the effective stimulated-emission cross section and the radiative lifetime is greater than at room temperature for all concentrations. Product στ is nearly independent of Yb3+ concentration at a given temperature. These results will aid in the design of high-power thin disk lasers by use of highly doped Yb:YAG. © 2003 Optical Society of America.
