Excimer lasers are currently the most suitable light source for fabricating fiber Bragg gratings. They can provide two effective writing wavelengths, 193nm and 248nm, and have high single-pulse energy, allowing writing on fiber gratings with weaker photosensitivity and enabling online fabrication of fiber Bragg gratings.

Currently, the main grating fabrication methods include: excimer laser interference, single-pulse writing of fiber Bragg gratings, and the phase mask method.

The FBG series excimer lasers produced by our company can be applied in the production of fiber Bragg grating etching, with the following advantages:

1. Uniform beam distribution, stable performance, and high cost-effectiveness.

2. Easy maintenance, low cost, fast response, and guaranteed after-sales service.
