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K_(3)B_(6)O_(10)Br(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d 33=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。High optical quality ultraviolet nonlinear optical(NLO)crystal K_(3)B_(6)O_(10)Br(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 d 33 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.
