摘要
详细研究了两种新型铁电液晶的非线性光学性质,液晶分子倾斜角θt、色散折射率,双折射率,双轴折射率和非线性光学系数各分量dij,两次谐波信号强度受外加电场及温度的影响,并分析了液晶分子结构与非线性光学性质的关系。
The nonlinear optic properties are studied of two novel ferroelectric liquid crystals,including the molecular tilt angle t, dispersion refractive index,birefringence,biaxial refractive index,and a number of independent dij coefficients.The temperature and the electronic field dependence of the nonlinear optic properties are analyzed.
