Popis:	We report two completely passive solutions enabling perfect stabilization of the Brillouin lasers with doubly-resonant cavities. The first laser configuration was stabilized through self-injection locking mechanism implemented to the laser cavity with DFB semiconductor pump laser. Second configuration included a nonlinear fiber mirror based on the population inversion dynamical gratings induced in low-absorbed Er-doped fiber. In both cases, the operating wavelength of the pump laser occurred to be locked to the ring resonance frequency leading to effective generation of Brillouin Stokes radiation. The pump-to-Stokes conversion efficiency of ~40% and the Stokes linewidth of
