Properties and Defects of Sr2+-doped α-BBO Crystal

Abstract

Abstract: High-quality Sr²⁺-doped α-BBO crystals were grown by the Czochralski method. The result of X-ray diffraction indicates that the grown crystals are α-BBO crystal. The results of transmission and birefractive indices show that Sr²⁺ ions
do not affect the optical properties of α-BBO. The measurements of DSC-TG and thermal expansion coefficient of Sr²⁺-doped α-BBO crystal manifest that Sr²⁺ ions also do
not influence the thermal properties of α-BBO. Meanwhile, the study of defects investigated by chemical etching illustrates that the quality of seed crystal is the most important factor of the quality of as-grown crystals.

Key words: Sr²⁺-doped high-temperature phase barium metaborate, optical properties, thermal properties, defects
