Abstract

The doped nonlinear optical crystal, ytterbium: yttrium aluminum borate, Yb3+:YAl3(BO3)4, has been grown with good optical quality in a high-temperature solution from K2Mo3O10 and B2O3 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-1. The emission lifetime, the absorption cross section, and the peak emission cross section are 0.68 ms, 3.4 × 10-20 cm2, and 0.8 × 10-20 cm2, 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.
