Paper Abstract

Birefringence dispersion seems to play at least an equal role to birefringence spatial inhomogeneity itself in many optical applications of crystalline materials including especially retardation plates, generators of the 2nd and higher harmonics, or polarizers. Mapping of parameters associated with birefringence dispersion on the entire areas of wafers cut out from crystalline boules seems then to be a powerful tool in testing and research works dealing with optical materials. The method of birefringence dispersion mapping and an automated, computer-controlled spectropolarimeter have been described. Its working has been illustrated by mapping of birefringence dispersion in Cu-doped LiNbO3 influenced by gamma irradiation and thermal annealing.
