Abstract: Application of femtosecond point-by-point inscription technique make it possible to form fiber Bragg gratings (FBGs) in different cores of multicore fibers as mirrors of laser cavity. In this paper, we present various configurations of Raman laser based on dual-core fiber. Due to the use of the inscribed FBG in the cavity of dual-core fiber, lasing threshold is reduced and the output power stability is increased, comparing to existing schemes.
