    Notes: 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.

    Notes: Abstract. We present a general modeling of a multi-longi-tudinal-mode bipolarized Nd-doped fiber laser which keeps both vectorial (polarization) and longitudinal properties in the dynamical equations. We use an approach based on random orientation of the microscopic dipoles and demonstrate that it is isomorphic to the model derived assuming a transverse two-site distribution function for the ions. This result is also true under the mean-field approximation. At steady-state, the model is the generalization of Rigrod’s theory to the case of a bipolarized laser.
