摘要: 采用顶部籽晶溶液生长法成功生长出尺寸为42 mm×20 mm×18 mm的高光学质量的紫外非线性光学晶体K3B6O10Br(KBB)。根据其结构对称性要求,将KBB晶体定向加工成不同的器件切型,系统表征其光电性能。对KBB晶体电弹常数进行了系统的表征,受微观结构影响,压电常数各向异性较大,最大的压电常数d33=6.69 pC/N。KBB晶体具有良好的激光频率变换、电光及压电性能,在光电子领域显示出潜在的应用前景。

Abstract: High optical quality ultraviolet nonlinear optical (NLO) crystal K3B6O10Br (KBB) with dimensions of 42 mm×20 mm×18 mm was successfully grown by the top-seeded solution growth method. According to its structural symmetry requirements, the crystal was cut and fabricated into different devices for the complete characterizations of its photoelectric properties. Additionally, the electric-elastic constants of the KBB crystal were systematically characterized, and the significant differences in piezoelectric anisotropy are observed due to its microscopic structure. The maximum piezoelectric constant d33 is measured to be 6.69 pC/N. Considering its good NLO frequency conversion, electro-optical and piezoelectrical properties, KBB crystal shows potential applications in the optoelectronics fields.
