摘要：

The potential of the dynamic holography method for testing the phase optical homogeneity of media transparent in visible light has been considered. This method is based on imaging samples in the scheme of two-wave mixing of the second-harmonic radiation of a Nd:YAG laser and image amplification in a photorefractive barium-strontium niobate crystal. Examples of identifying phase inhomogeneities at a level of 10(-5) cm(-1) and less in crystals of different compositions are presented.
