Abstract
The obvious influence of the internal photoinduced electric field on the formation of self-pumped phase conjugation in doped (K(0.5) Na(0.5))(0.2) (Sr(0.75) Ba(0.25))(0.9) Nb(2)O(6) crystals has been investigated with intermittent and continuous laser beams. An analysis is given that involves the migration of charge carriers driven by the photovoltaic (PV) and the pyroelectric (PY) electric field. Deviation from the optimal state of energy transfer owing to the PV effect and the self-adjusting of holograms owing to the PY field are the two important dominant processes in the self-pumped phase conjugator. The influence of the photoinduced electric field on the conjugation fidelity and the stability of the phase-conjugate output is also observed and analyzed. The bump feature of the two-wave mixing and the oscillating situation of the self-pumped phase conjugator are observed and are explained in view of the photoinduced internal field.

Main findings
The study investigated how an internal photoinduced electric field influences self-pumped phase conjugation in doped (K0.5Na0.5)0.2(Sr0.75Ba0.25)0.9Nb2O6 crystals using intermittent and continuous laser beams. The analysis attributes observed behavior to charge-carrier migration driven by photovoltaic and pyroelectric electric fields, including deviation from optimal energy transfer (PV effect) and self-adjustment of holograms (PY field), and reports observed effects on conjugation fidelity and output stability.
