Abstract

Measurements are reported of the spectroscopic properties (absorption and emission spectra, stimulated-emission cross section, and radiative lifetime) of $({\mathrm{Yb}}_x{\mathrm{Y}}_{1-x}{)}_3{\mathrm{Al}}_5{\mathrm{O}}_{12}$ 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 ${\mathrm{Yb}}^{3+}$ 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 ${\mathrm{Yb}}^{3+}$ 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.
