中文摘要：
本文讨论了影响BaAlBO3F2（BABF）晶体生长尺寸和质量的相关因素，诸如助熔剂的选择、生长原料的制备、籽晶的处理、温度梯度、晶体转速、降温速率等。采用新的B2O3-LiF—NaF助熔剂体系，[001]向籽晶，20—40r／min的转速，1～5℃／d的降温速率，通过中部籽晶法生长出了尺寸为40×30×12mm3、光学均匀性为△n≈4．048×10^-6／cm的BABF晶体。
英文摘要：
The study focused on optimization of growing conditions of new nonlinear optical crystal BABF. Flux selection, preparation process of starting materials and optimization of other growing parameters were discussed in the paper. The high-quality BABF crystal with sizes up to 40 × 30 × 12 mm3 had been successfully grown by the middle-seeded solution growth technique, and the optical homogeneity of the crystal is △n ≈ 4. 048 × 10^-6/cm. The growing conditions are as follows： B2O3-LiF-NaF system as fluxes, [ 001 ] seed orientation, rotation rate 20-40 r/min, cooling rate 1-5 ℃/d.
