摘要

我们研究了硼酸盐家族的三角形晶体α-BaB2O4和β-BaB2O4的声学、光学和声光性质。在晶体中计算了声波的相速度和极化，以及Bragg角的频率依赖性。根据声波相速度的方向，在材料的XZ和YZ平面上评估了性能图的大小。进行分析是为了寻找将该材料用于工作在紫外光谱区的声光器件的可能性。

Physical Properties of Barium Borate Crystals Promising for Applications In Acousto-Optic Devices

We examine acoustic, optic and acousto-optic properties of materials belonging to the borate family of trigonal crystals α-BaB2O4 and β-BaB2O4. Phase velocities and polarizations of acoustic waves, as well as frequency dependences of Bragg angles, are calculated in the crystals. Figure of merit magnitudes are evaluated in XZ and YZ planes of the materials depending on the direction of phase velocities of acoustic waves. The analysis is carried out in order to find a possibility of using the materials in acousto-optic devices operating in the ultraviolet region of spectrum.
