Paper Abstract

The theory of a self-pumped phase conjugator (SPPC) for speedily amplitude-modulated beams is presented by combining DFWM theory of speedily amplitude-modulated beams in photorefractive (PR) crystal with the model of two interacting regions for SPPC. The field expression of phase conjugate beam is given. For the special case of code modulation the phase conjugate reflectivity is calculated. The experimental result using code modulation shows that SPPC is endowed with the ability of processing speedily modulated information in the temporal domain.
