Double-Pulse One-Way Imaging by using Degenerate Four-Wave Mixing

Abstract

The paper presents novel methods for one-way imaging by double-pulse transmission through a turbulent medium, using corrected wavefront generation due to degenerate four-wave mixing. The present methods are based on a principle that the mixing of a distorted object pulse with a pump pulse equivalently distorted through an identical turbulent medium produces corrected wavefront in a nonlinear medium in real-time. These methods require neither retroreflecting transmission of a phase-conjugate wave nor two fibers with the same length and quality. Two methods associated with the basic principle are presented and theoretically discussed with ability of arbitrary phase correction.
