Resonant loop mirror with narrow-band reflections and its applications in single-frequency fibre lasers
R.Paschotta, D.J.B.Brinck, S.G.Farwell, and D.C.Hanna
We present a new form of loop mirror (to be realized with all-fiber or integrated optics technology) that can produce narrow-band reflections and could find an application in single-frequency fiber lasers, allowing for a standing-wave design with a long doped section and eliminating the need for a Faraday isolator or a fiber grating. We discuss the main features of such a loop mirror and present experimental results that agree well with the theory.
