Yttrium aluminate (YAlO3)

Yttrium aluminate (YAlO3, YAP) single crystal belongs to the Orthorhombic crystal system. It is an important crystal matrix material similar to YAG single crystal. It has excellent optical, physical and chemical properties, good mechanical hardness, high refractive index, excellent optical transparency, high thermal conductivity and good thermal stability. It is widely used in laser technology, especially as the gain medium and optical components of lasers, such as prisms and lenses. Its excellent optical properties make it widely used in high power and ultraviolet laser systems. In addition, YAP is also used as a material for scintillation detectors, and in Nuclear medicine and particle physics research γ X-ray and high-energy Particle detector. YAP crystals doped with rare earth and transition metal ions have wide applications in laser, scintillation, and holography. Recording and optical data storage, ionization Dosimeter, High-temperature superconductivity thin film substrate and other fields.
