    Shanghai North Optics provides Yttrium Orthoaluminate YAlO3(YAP) crystal substrates. With a perovskite-like orthorhombic crystal structure, lattice constant a=5.176 Å, b=5.307 Å, c=7.355 Å, YAP substrate is often used for the growth of high-temperature superconducting (HTS) thin film, II-V nitride, and oxide films. Yttrium Aluminum Oxide (YAP) is a transparent crystal with a wide band gap, making it suitable for applications in the near-infrared (NIR) region. Rare earth and transition-metal ions dopants located in YAP substrates find wide uses for applications in lasers.
