Paper Abstract

Crosstalk between two beams incident on a phase-conjugating four wave mixer (FWM) was investigated as a function of beam input angles and beam intensities for the case where both input beams and the FWM pumps were the same frequency. Intensity crosstalk in the conjugated return beams was observed. Spatial image crosstalk was also observed. Analysis shows that spatial and intensity crosstalk arise from the same mechanism, a competition for pump intensity that occurs when the sum of the probe and noise intensities is more than a few percent of the pumps. A model of this mechanism has been developed that permits quantitative prediction of intensity crosstalk.
