title = "Astigmatism-controlled beam shaping for high-quality fibre Bragg grating inscription using femtosecond laser",
abstract = "We present an astigmatism-controlled beam-shaping technique for femtosecond laser inscription of FBGs, optimizing beam profiles using a cylindrical lens to mitigate focal distortion and enhance grating quality. This method improves reflectivity, reduces insertion losses, and expands grating dimensions, offering a scalable solution for advanced optical communication and sensing.",
