Abstract
We present new, easy to use methods of measuring the fidelity of phase conjugated beams employing a classical system for image acquisition and processing, coupled to a personal computer. Two methods are based on intensity distribution changes measurements and the third is an interferometric evaluation of the wavefront reconstruction. These methods are applied in phase conjugation fidelity studies in a degenerate four wave mixing experiment using a He-Ne laser and a Bi12TiO20 (BTO) photorefractive crystal. A comparison between the proposed methods, and also with other techniques currently used for phase conjugation fidelity studies, is made.
