By using Nd∶YAG mode locked pulse laser (λ=532 nm, τ 0=35 ps), the third order nonlinear optical susceptibility χ (3) , and time response properties of liquid crystals containing Schiff base and Naphthalimide are measured with forward degenerate four wave mixing (DFWM). The corresponding nonlinear refractive index coefficient n 2, second hyperpolarizability γ (3) are calculated. The mechanism for their nonlinear effect is discussed.
