Transient Phase Conjugation.
Abstract
During the past 3 years, material damage thresholds have been investigated as well as the magnitudes and response times of nonlinear susceptibilities of several important classes of optical materials. In addition, the Modified Twyman-Green Interferometer (MTGI) was invented. The MTGI determines both the magnitude and phase of the nonlinear susceptibility of a material relative to a known standard. This device has found significant acceptance within the optics research community. A phenomenon where energy may be exchanged between two frequency degenerate laser pulses has been characterized. Experimental investigations of optical phase conjugation via degenerate four wave mixing and beam coupling via degenerate two wave mixing using several nonlinear materials are compared. The components of the various physical phenomena which determine a nonlinear optical response as well as the interactions between these components are described. The strengths and weaknesses of the various optical materials and the utility of the MTGI are discussed. Finally, directions for future research are suggested.
