    Additive-modulation-instability ring laser in the normal dispersion regime of a fiber

    No full text
    A synchronously pumped modulational-instability ring laser with a nonlinear dispersive fiber can be operated in both the anomalous and the normal dispersion regimes. We obtain simple analytical expressions for the sideband gain in the cavity by using an average pulse formalism. The numerical simulations indicate that stable stationary trains of pulses may be formed in the cavity. This is independent of the sign of the dispersion. © 1992 Optical Society of America.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
