Abstract

By using a self-pumped conjugator (Cat conjugator) it is demonstrated to produce the phase conjugate reflection of double signals, induced by the self-pumped phase conjugation, in a 16 degree(s) cut Cu-doped KNSBN photorefractive crystal. On various experimental conditions, the phase conjugate reflectivities of signals were measured versus the pump-signal beam ratio. A comparison was made between the signal's reflectivities in 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.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
