| Реферат: | eng: Crystal growth of α-BBO in a modified low-gradient Czochralski furnace was performed. The distribution of temperature inside the furnace was described by a three-fold symmetry axis (L3). The axial temperature gradient under the melt was ∼2 K/cm, while that inside the melt was almost equal to zero. A 36 mm thick sample of the grown crystal shows extremely low 0.05 cm-1 absorption coefficient at wavelengths >220 nm. © 2010 Elsevier B.V. All rights reserved.
