HIGH-RESOLUTION PHASE-CONJUGATE IMAGING IN DOUBLE-PUMPED PHASE CONJUGATORS

摘要

Phase-conjugate images with a resolution greater than 250 lines/mm are obtained through the use of a bridge, double-pumped phase conjugator. We demonstrate that this conjugator can carry out image-processing tasks, such as the addition and subtraction of complex spatial distributions, with a spatial resolution of > 100 lines/mm. These results represent a significant improvement over previously reported resolutions obtained from photorefractive mutually pumped phase conjugators and approach the theoretical limit imposed by the grating spacing and cross talk.
