Does femtosecond laser fabrication of FBG require photosensitive fiber?

No, it does not. Femtosecond lasers can directly penetrate the fiber coating and write gratings in the fiber core. The applicability of ordinary single-mode fiber, pure silica fiber, radiation-resistant fiber, and even materials such as sapphire can all be discussed.

Can multiple sensors be made on a single fiber?

Yes. The femtosecond laser fabrication method supports integrating multiple sensors on a single fiber. For specific quantities, spacing, and wavelength allocation, please contact us to confirm.

Detailed Introduction

The femtosecond laser fabrication FBG solution we provide centers on using a femtosecond laser to directly penetrate the fiber coating and inscribe a grating in the fiber core, eliminating the dependence on photosensitive fiber. This method is applicable 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 retained to a large extent. For projects requiring high-temperature resistance, corrosion resistance, or the integration of 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.
