Abstract—

We have studied the acoustic and optical properties of a LiBi(MoO₄)₂ crystal prepared by low thermal gradient Czochralski growth and determined the complete elastic modulus matrix of the crystal. Ultrasound attenuation for a wave traveling along the Z axis of the crystal has been assessed in the frequency range 40–170 MHz. We have measured refractive indices of the crystal in the visible and near-IR spectral regions and obtained their spectral dependences using the Sellmeier formula. The conclusion is made that such crystals are potentially attractive for producing acousto-optic modulators.

LiBi（MoO 4）2晶体的声学和光学性质

摘要-

我们已经研究了通过低热梯度直拉生长法制备的LiBi（MoO ₄）₂晶体的声学和光学性质，并确定了晶体的完整弹性模量矩阵。在40-170 MHz的频率范围内评估了沿晶体Z轴传播的波的超声衰减。我们已经测量了晶体在可见光和近红外光谱区域的折射率，并使用Sellmeier公式获得了它们的光谱依赖性。得出的结论是，这种晶体对于生产声光调制器具有潜在的吸引力。
