Parametric self-pumped phase conjugation of the space heterogeneous light beam in an inverted Nd:YAG-rod with nonreciprocal feedback is investigated. The effect was realized in the geometry of the near-corunning mutually-incoherent pumping beams (incident and passing through the feedback loop with phase and amplitude nonreciprocities). Phase conjugation was observed both for the linearly polarized pumping beams and for their circular polarizations. [References: 7]
