Abstract.
We present a steady-state analysis of a general model for a bipolarized Nd-doped fiber laser including the slow longitudinal variations of the dynamical variables. The combined effects of pump-induced, distributed, and localized anisotropies are studied versus the fiber length. In particular, the evolution of the thresholds versus the pump-input polarization angle, for different fiber lengths, is investigated in depth. Approximate analytical results are derived for the thresholds and the output intensities. A good agreement with the numerical simulations is achieved in a large range of parameters.
