The optical absorption and emission intensity of luminescent and birefringent crystal ErBa3B9O18 were examined from optical absorption data based on Judd-Ofelt theory. The three intensity parameters () are 3.10 × 10−20, 0.87 × 10−20, and 1.80 × 10−20 cm2, respectively. From the obtained intensity parameters, the radiative probabilities , radiative lifetime , fluorescence branching ratios , and integrated emission cross sections have been calculated. In comparison with other Er-doped luminescent crystals, ErBa3B9O18 may find application in thin disk laser.
