Femtosecond laser fabrication of FBG
The femtosecond laser-based FBG fabrication solution we offer centers on using a femtosecond laser to directly penetrate the fiber coating and inscribe gratings in the fiber core, eliminating the dependence on photosensitive fiber. This approach can be applied to ordinary single-mode fiber, pure silica fiber, radiation-resistant fiber, and materials such as sapphire; after inscription, the fiber's original mechanical strength is preserved to a large extent. For projects with high-temperature resistance and corrosion resistance requirements, or that need to integrate multiple sensors on a single fiber, this fabrication method provides a discussable process path. For specific fiber types, inscription parameters, sensor quantities, and delivery formats, please contact us to confirm the configuration.
