The main properties of the transient evolution and steady-state generation of fiber lasers with polarization domains of radiation in the laser resonator are investigated based on the constructed Lyapunov functional. The direction of the transient evolution is determined without restrictions on the parameters of the lasing model used and the initial conditions of the transient process. The obtained results are in good agreement with experimental data on the formation of laser radiation polarization domains and domain walls separating these domains from each other.

Keywords：polarization domains; fiber lasers; lyapunov functional
基于构建的Lyapunov泛函，研究了激光谐振器中具有辐射偏振域的光纤激光器瞬态演化和稳态生成的主要特性。在不施加任何限制于所用激光模型参数和瞬态过程初始条件的情况下，确定了瞬态演化的方向。所得结果与实验数据关于形成激光辐射偏振域及其分隔这些域之间的畴壁的一致性良好。
