Correction of Phase Distortions by Nonlinear Optical Techniques
Abstract
The effort in this program is divided into three tasks, The first task is an experimental effort to explore the physics of phase conjugation via four-wave mixing in the visible with emphasis on the blue-green and ultraviolet region of the spectrum using appropriate dye lasers. Issues such as degree of correction, efficiency, and required pump wave properties will be addressed in this task. In addition, we will determine the efficiency of conjugate wave generation as a function of detuning of the pump frequency from the probe frequency a concept which has direct impact on systems concepts. The second task concentrates on expanding our understanding of the theory of four-wave mixing with emphasis on the pump manipulation and polarization rotation issues and on those features that maximize the efficiency of the process, such as resonant enhancement. In addition, on this task we will select material candidates that show promise for high-power application in the blue-green and UV. The third task will concentrate on the systems-related issues of nonlinear phase conjugation with emphasis on systems of interest to DARPA. We will expand our analysis of the concepts generated and generate new concepts. We will also identify critical technologies for high-power application of nonlinear phase conjugation to DARPA systems.
