Abstract

The theoretical and experimental investigation of the kinetics of photoanisotropy induction in polarization-sensitive media with significant dark relaxation on the basis of azo dyes in polymer matrices is considered. For improving dynamic characteristics of polarization-sensitive materials, new azo dye N,N-dimethyl-4((4-nitrophenyl)diazenyl)aniline has been specially synthesized, and the kinetics of photoanisotropy induction and relaxation in materials on the basis of this dye has been compared with materials on the basis of Dimethyl Yellow. It is shown that spectral sensitivity of the material with new azo dye is in the range of 470520nm, the working range is both in the visible and in the infrared range (from 520nm at least up to 3400nm), the maximum meaning of effective anisotropy is 38% (Δn0.022), and the time of photoanisotropy inducing and erasing is approximately 18ms. It is shown that, if we confine ourselves to meanings of effective anisotropy of approximately 1–2% (Δn0.007), the time of inducing/erasing will be of the order of microseconds. The use of such dynamic polarization-sensitive materials gives the possibility of a new direction—dynamic polarization holography to be developed that com bines the possibilities of both dynamic and polarization holography and that opens new prospects for applications.
