Paper Abstract

New phenomena are observed theoretically in nonlinear optical responses of polydiacetylene-toluene sulfonate (PTS) irradiated by a strong laser beam. Within a two-level model of PTS the transient behavior of the induced susceptibility is investigated. Optical nutation is found and the optical Stark blue shift and bleaching are also found in qualitative agreement with experiments. In the steady state a new type of optical tristability mediated by phonons is found. A possible mechanism responsible for this tristability is discussed. 1 .
