Abstract

This paper presents the results of a study of the features of photoinduced light scattering in photorefractive lithium niobate crystals. The causes are discussed for the appearance of additional asymmetry of the scattering pattern when a beam with a nonplanar wave front is used for pumping. Results are presented from an experimental study of how laser radiation having an irregular wave front interacts with photoreactive lithium niobate crystals.
