Imaging through Turbulent Media Based on Phase Conjugation in Resonantly-Enhanced Second-Order Nonlinear Materials: A Novel Scheme

Abstract

During the funding period, we have made a significant progress towards the objectives being set on a class of the important research projects. The major accomplishments include: * Theory of phase conjugation based on second-order nonlinear parametric processes under a novel configuration * Generation of phase-conjugated beam based on second-order nonlinear parametric processes, supporting our theory * Demonstration of phase conjugation that is insensitive to polarization of the input beam * Achievement of broadband phase conjugation * Restoration of blurred images due to phase distortion, supporting out theory * Demonstration of image restoration which is insensitive to the polarization direction and wavelength of the input beam. As a result of our extensive research, we have made paramount contributions to the long-term mission of the U.S. Air Force. In particular, our results on the restoration of the images will enable us to remove the effects caused by the atmospheric turbulence. Therefore, we will greatly improve the sensitivities and resolutions for imaging and free-space communications.
