N2 - A bulk β-BaB2O4 crystal was grown from a novel BaB2O4-NaBaBO3-BaMoO4 ternary solvent system with an optimal solvent composition using top-seeded solution growth (TSSG) and its optical properties were compared to those of a reference crystal grown from the conventional binary BaB2O4-NaBaBO3 system. The linear absorption spectrum was measured for both polarizations over an exceptionally broad range from ultraviolet (UV) to terahertz (THz) range (0.2-1500 μm), revealing high transparency and low absorption coefficients, indicative of excellent material uniformity and purity. Nonlinear optical (NLO) performance was evaluated via second-harmonic generation (SHG) at 266 nm, showing comparable efficiency to the reference sample. These results demonstrate that the ternary system enables scalable crystal growth with preserved high optical quality, making it a promising candidate for industrial production of nonlinear optical elements.
