✦ Synopsis

The phase conjugate re ection of double signals, induced by the self-pumped phase conjugation, is demonstrated in a 16 • cut Cu-doped potassium sodium strontium barium niobate (KNSBN) photorefractive crystal. The phase conjugate re ectivities of signals were measured versus the pump-signal beam ratio. A comparison was made between the signal's re ectivity with and without the presence of the other signal beam. The multi-region four-wave mixing model within the same crystal has been employed to explain the geometry performance and the experimental results.
