摘要

We present experimental results showing an improvement in the spatial resolution of phase conjugate images obtained from mutually pumped phase conjugators. Resolutions of >100 lines/mm are presented and we demonstrate that this resolution can be achieved while performing image processing tasks such as the addition and subtraction of complex spatial distributions. These results represent greater than an order of magnitude improvement over previously reported resolutions obtained in photorefractive mutually pumped phase conjugators and approach the theoretical limit imposed by the grating spacing and crosstalk
