Abstract
We propose a modified scheme of a four-wave-mixing phase- conjugate mirror with the feedback comprising a nonreciprocal Brillouin amplifier placed inside the feedback loop. A simulation of the loop scheme showed the unidirectional oscillation of a phase-conjugate wave to be feasible in the optimum mode of operation of the loop-type PC mirror when the energy of a probe wave at the SBS amplifier input is more than an order of magnitude lower than the SBS threshold. Our experiments demonstrated that the proposed scheme of the loop-type PC mirror ensured pulse-to-pulse stable unidirectional oscillation of a phase- conjugated wave. The characteristics of the output radiation are studied and the high phase conjugation fidelity is demonstrated. The problems arising in scaling up the PC mirrors of such a type are considered.
