Measurement of the giant nonlinear response of dye-doped liquid crystals

Abstract : We present an experimental method for measuring the nonlinear optical response of a dye-doped liquid crystal cell. We show that a very large response is obtained for a very low input light intensity. The nonlinear optical response as a function of the dye concentration in the liquid crystal host is characterized by the optical nonlinear coefficient n2. The experiment provides advanced undergraduate students experience in soft matter and nonlinear optics
