Paper Abstract

Time-dependent elliptic light fields were realized and investigated first. They were created by the dynamic system 'laser light>LiNbO3:Fe crystal' and measured by the elaborated acquit-action (1s) real-time Stokes polarimetry what insures measurements of all Stokes components at practically the same state of dynamic system and investigated field. The interval between cloze-ups (15s) was two orders less then full topological 'life story' of an individual C point pair. Regularities of singularities topological space-time dynamics of azimuth networks, optical diabolos pairs and handedness areas were established. It was found that macroscopic (total) development of singular elliptic speckle patterns is irreversible contrary to fully reversible microscopic (local) transformations of field smooth parts to singular states and back which occur independent in space and time. Their scenarios contain obligatory pre-nucleation ('embryo') and after-annihilation ('decay') states. Elaborated approach and presented results start dynamic singular optics of time-dependent elliptic light fields. It has established topological scenario of singularities nucleation/annihilation processes in developing generic elliptic light fields.
