Abstract

The cholesteric liquid crystal (CLC) layers show circular dichroism and thus they can be used in circular optical polarizers. The paper includes the analysis of conditions which the CLC material -for such a polarizer should fulfil. Cholesteric materials for circular polarizers of Nd glass laser radiation were selected. The dependence 0-F the CLC layers transmission on its temperature and thickness and on the radiation power density was investigated. Polarization properties of the CLC layers were investigated too. The optical quality of a model of liqud crystal polarizer was also researched.
