摘    要:
An investigation is carried out on the linear and nonlinear optical properties of quasicrystaJs. The linear and nonlinear susceptibilities are determined for two- and three-dimensional ctuasicrystals. The results show that for optical linearity, two-dimensional quasicrystals are uniaxial, while icosahedral quasicrystals are optically isotropic. Meanwhile all ctuasicrystals, except those with 5, 5m, N, Nmm (N = 8, 10, 12) symmetries, have no the firstorder optical nonlinearity. The tensor scheme of the first order nonlinear susceptibility is the same for these eight exceptional kinds of quasicrystals.
