Lead molybdate (PbMoO4) is a birefringent optical crystal that exhibits strong birefringence and a high refractive index. It has a tetragonal crystal structure and is used in a variety of optical applications.
One of the main applications of PbMoO4 is as a material for the fabrication of acousto-optic devices. When a sound wave is propagated through a PbMoO4 crystal, it generates a periodic modulation of the refractive index in the crystal, which can be used to control the polarization and intensity of light passing through the crystal. Acousto-optic devices based on PbMoO4 are used in various applications, such as laser beam deflection, modulation, and switching.
PbMoO4 is also used as a birefringent material in various optical devices, such as wave plates, polarizers, and frequency doubling crystals. Its strong birefringence allows it to split light into two orthogonal polarizations, each traveling at a different speed and refracting at different angles.
In addition to its optical applications, PbMoO4 is also used in the production of scintillation detectors, due to its ability to convert high-energy radiation into visible light. It is also used as a material for high-temperature piezoelectric sensors and actuators, as it exhibits high thermal stability and piezoelectric properties at elevated temperatures.
