Paper Abstract

The nonlinear optical phase conjugation (NOPC) is an important field of modern optics with applications in the compensation of aberrations in laser systems, image processing, and optical measuring systems. Interferometers with PC-mirrors (PCM) offer a higher accuracy of measurement and the possibility of phase measurement with no additional reference waves. The successful application of NOPC very strongly depends on the PC-materials. So, for example, photorefractive materials like BCO-crystals have a high sensitivity connected with low response times, but their applications as PCM's in interferometers requirers the exact knowledge and characterization of the quality of the phase conjugation process both with respect to the amplitudes and the phases of the signal Wayes and the correspondend spatial and temporal behavior.
