Paper Abstract

He-Ne laser (0.63 mkm) initiates developing singular speckle-fields due to «optical damage» in photorefractive LiNbO3: Fe crystal. They were investigated by techniques of dynamic stocks-polarimetry, monstardom and polarization characteristics of optical vortices combined with morphology of polarization singularities. Ergodicity of dynamic speckle-fields was found. It was shown that sign of C points coincides with speckle handedness they are nested; stars/monstar, lemon are underlined by negative/positive OVs. General regularities of dynamic elliptic speckle-fields development were established.
