Seminar: “Correlation between Parameters of Optical Field Angular Momentum in the Vicinity of Optical Singularity" by Prof. Igor Mokhun
Friday, January 24, 2014 4:00 PM to 5:00 PM
CREOL Room 102

Abstract:
The relations between distributions associated with different optical parameters are considered. Such kinds of relations are analyzed: intensity – polarization; intensity – azimuth of transversal Poynting vector component; azimuth of transversal Poynting vector component – modulus of this component; azimuth of transversal Poynting vector component – polarization. It is shown that such relations may be realized as correlation or “anticorrelation”. For example, intensity of field has small gradient in areas where the polarization changes quickly. The method of measurement of characteristics of Poynting vector components is proposed. The results of experimental confirmation are presented. The angular momentum in the area of C-point (point of circular polarization) is considered. It is shown that spin angular momentum of quasi-chromatic “simple” beam like Gaussian practically does not depend on time coherency. The results of experimental investigations are presented.
