Here is a list of common nonlinear optical crystals and their properties:
In standard (linear) optics, the polarization of a material responds linearly to the electric field of light. In nonlinear optics, high-intensity light (usually from a laser) causes the material to respond in a non-proportional way. crystal nonlinear optics with snlo examples pdf

Nonlinear optical effects occur when a high-intensity light beam interacts with a nonlinear optical material. The nonlinear response of the material can cause a variety of effects, including: The nonlinear response of the material can cause
Key processes depend on the lowest nonzero nonlinear susceptibility: second-order (χ(2)) processes occur in noncentrosymmetric crystals; third-order (χ(3)) processes occur in all media but are weaker.
