The paper reports the inscription of second- and third-order fiber Bragg gratings (FBGs) in single-mode optical fiber (SMF-28e+) via the line-by-line (LbL) and the point-by-point (PbP) methods using femtosecond laser radiation. The use of these methods jointly with based on an automatic spatial deviation correction system is considered. The approach allows to significantly improve spectral characteristics of FBG without the loss of fabrication performance.
