Current status of recently proposed novel approach to inertial fusion energy technology, where phase conjugating mirrors generated by stimulated Brillouin scattering are employed to take care of automatic self-navigation of every individual laser beam on injected pellets, has been reviewed. This novel technology is of a particular importance to the direct drive schemes of pellets irradiation as assumed, e.g., in HiPER project. If successful also in its full scale realization, such an aiming scheme would greatly reduce the technical challenges of adjusting large and heavy optical elements on each shot in a system with a repetition rate of at least several Hertz. In the gradual step-by-step tuning of this technology, in this paper a close attention has been paid to the unconverted basic harmonic issue with a special Faraday isolator design proposed. However, a practical realization of this component in its simplest form might be somewhat difficult to achieve due to a suitable optical material shortage. Hence, a more elaborate scheme of this isolator which would make its realization much more realistic even for optical materials currently available has been examined and will be presented.
