In this paper, the authors proposed a new optical scheme for providing passive mode locking in a fiber ring laser. The idea is to use a liquid crystal display (LC) cells for the realization of nonlinear polarization evolution. Also, in the work theoretically investigated the dispersion of optical fibers of different types to construct fiber lasers with ring resonators. Was studied the stability of polarization to ensure nonlinear evolution polarization, by solving the Ginzburg-Landau equation, and also the control of the polarization of the radiation by the LC cell using the Oseen-Frank equation.
