摘要： 采用提拉法生长了质量优异的掺Sr2+的α-BBO晶体,XRD结果证实所制备的晶体为高温相,透过率及双折射率分析显示掺Sr2+不影响α-BBO晶体的光学性能,DSC-TG分析及热膨胀系数的测量表明Sr2+的掺入对其热学性能的影响不大,同时还对晶体的缺陷进行了初步的研究,研究显示籽晶的完整性是影响晶体质量的重要因素。

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
