The materials that generates nonlinear polarization under the action of laser and external field, and has strong nonlinear interaction between light waves, and the nonlinear optical materials without symmetry center in structure is called second-order nonlinear optical materials; Those with symmetric centers are called third-order nonlinear optical materials. According to physical effects and applications, it can be divided into seven categories: laser frequeney conversion ma terials, such as frequency doubling, mixing, optical parametric oscillation and amplification materials; Electro-optical materials; Photo-refractive materials; Acousto-optic materials; Magneto-optical material; Photoinduced birefringent materials; Nonlinear light absorbing materials.
