摘要：

We have measured the tensor components c1111 and c1221 of third-order nonlinear optical susceptibility of two nematic liquid crystals, MBBA (p-methoxy-benzylidene p-n-butylaniline) and EBBA (p-ethoxy-benzylidene p-n-butylaniline), in the picosecond regime. We observed that the molecule with ethoxy group (EBBA) has a larger third-order nonlinearity than the one with methoxy group (MBBA) and present a model to explain this effect.
