Lead Molybdate (PbMoO4) is a crystalline material that belongs to the orthorhombic crystal system and is a popular material used as an acousto-optic crystal. Its high refractive index and good acousto-optic properties make it a suitable candidate for applications in high-performance devices such as Acousto-Optic Tunable Filters (AOTFs), Acousto-Optic Deflectors (AODs), and Acousto-Optic Modulators (AOMs). In these applications, the acousto-optic effect can be utilized to change the frequency or amplitude of light in response to an applied acoustic wave.
