Abstract

THe paper considers the possibility of application of doped chiral systems with properties of dynamic optical hysteresis as optical limiters. The theoretical analysis of interaction of transmitted radiation with a resonant absorbing chiral system is performed using both two-level and multi-level models of the absorbing center. Experimental values of nonlinearity threshold obtained for the system of ketocyanine - nematochiral liquid crystal were approximately 250 (mu) J/cm² at the wavelength of 530 nm.
