    YAG Optical Crystals

    Description

    Undoped Yttrium Aluminium Garnet (Y3Al5O12 or YAG) is a new substrate and optical material that can be used for both UV and IR optics. It is particularly useful for high-temperature and high-energy applications. The mechanical and chemical stability of YAG is similar to that of Sapphire, but YAG is not birefringent. This particular feature is extremely important for some optical applications


    Feature

    • Non-birefringence
    • Extremely hard and durable
    • High thermal conductivity
    • High bulk damage threshold
    • High index refractive

    Application

    • Laser igniters
    • Laser-induced breakdown spectroscopy
    • Optical substrates and windos
    • Particle image velocimetry
    • Cavity ring-down spectroscopy
    • Transparent electronic substrates
    • Right angle prism
