    Femtosecond Fibre Bragg Grating YOSC-FsFBG-15XX

    YOSC-FsFBG-15XX uses femtosecond laser to directly penetrate the coating layer of the fibre and write FBG onto the fibre core. It can be written with special optical fibres to ordinary communication optical fibres. Femtosecond laser direct writing FBG have high stability and can withstand temperatures up to 1000℃ in the grating area.
    Applications
    • Fuel cell
    • Low temperature, superconducting magnet
    • Oil and gas exploration
       
    Characteristics
    • The temperature resistance of the grating area reaches 1000℃
    • Written directly through the coating with high mechanical Strength
    • The grating area can be as short as millimeters, achieving point sensing and solving temperature strain cross sensitivity
    • Radiation resistance, and electromagnetic interference resistance
    • Customizable
