Abstract

The features of low-threshold limitation are observed. It is shown, that one of the solutions of this task is usage of effect of two-photon absorption in an impurity liquid crystal. It is stipulated by large cross-section of two- photon absorption in cyanobiphenyls. The strategy of usage of mesomorphic microlenses as structural elements of optical limiters is discussed. The experiments on optical limitation in constructions using mesomorphic microlenses are realized.
