Ol. Antipov et al., SELF-PUMPED PHASE-CONJUGATION OF THE HETEROGENEOUS LIGHT-BEAM IN THE INVERTED ND-YAG-ROD WITH NONRECIPROCAL FEEDBACK, Optics communications, 117(3-4), 1995, pp. 290-294
Parametric self-pumped phase conjugation of the space heterogeneous li
ght beam in an inverted Nd:YAG-rod with nonreciprocal feedback is inve
stigated. The effect was realized in the geometry of the near-corunnin
g mutually-incoherent pumping beams (incident and passing through the
feedback loop with phase and amplitude nonreciprocities). Phase conjug
ation was observed both for the linearly polarized pumping beams and f
or their circular polarizations.
