| Abstract: | The third order nonlinear optical properties of novel carboxylate anions with chiral amines and ammonium cations have been studied by a new alternative of the classical z-scan technique with picosecond laser pulses (pulse duration of 30 ps at 1064 nm wavelength). The materials do not present linear and nonlinear (two-photon) absorptions at the wavelength and the intensities used for the experiments. The non-resonant molecular second order hyperpolarizability γ obtained can reach 4.4 × 10−48 SI. These values are two and three orders of magnitude larger than those CS2 and of C6H6 respectively. |
