The dependence of the elastic and acousto-optic properties of lead molybdate crystals on the direction of the wave vector and the polarization of acoustic and optical waves has been studied. The effective photoelastic constants were determined by the Dixon method for various geometries of the Bragg light diffraction. The dependence of the acousto-optic quality factor on the direction of the wave vector of longitudinal acoustic waves in the symmetry plane has been studied in detail. It is shown that in this case the largest and smallest values of the acousto-optic quality factor are observed when light is diffracted by pure longitudinal waves in this plane. It is also shown that the values of the acousto-optic quality factor in lead molybdate crystals are practically the same as in paratellurite crystals.
研究了钼酸铅晶体的弹性和声光特性对波矢方向以及声波和光波偏振的依赖性。通过狄克逊方法针对布拉格光衍射的各种几何结构确定了有效光弹常数。详细研究了声光品质因数在对称平面内纵向声波波矢方向上的依赖性。结果表明，在这种情况下，当光在该平面内被纯纵向波衍射时，观察到声光品质因数的最大值和最小值。还表明，钼酸铅晶体中的声光品质因数的值实际上与亚碲酸盐晶体中的相同。
