Abstract
The possibility of using doped chiral systems, which show the property of t he dynamic optical hysteresis, as optical limiters is considered. A theoret ical analysis of the interaction of the transmitted radiation with a resona ntly absorbing chiral system is carried out using a two-level model of the absorbing center. The experimental value of the nonlinearity threshold, obt ained for a ketocyanine-nematochiral liquid-crystal system, is similar to 2 50 mu J/cm(2) at a wavelength of 530 nm.
