The doped nonlinear optical crystal, ytterbium: yttrium aluminum borate, Yb<sup>3+</sup>:YAl<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub>, has been grown with good optical quality in a high-temperature solution from K<sub>2</sub>Mo<sub>3</sub>O<sub>10</sub> and B<sub>2</sub>O<sub>3</sub> fluxes. Room- and low-temperature absorption and fluorescence spectra have been measured, and spectral parameters have been calculated. The ground-state energy-level splitting is 581 cm<sup>−1</sup>. The emission lifetime, the absorption cross section, and the peak emission cross section are 0.68 ms, 3.4×10<sup>−20</sup> cm<sup>2</sup>, and 0.8×10<sup>−20</sup> cm<sup>2</sup>, respectively. In comparison with established laser crystals, the results for the cross sections, lifetime, and energy splitting suggest that this crystal has potential as an efficient self-frequency-doubled laser operating in the green.
