Nonlinear Crystals

Nonlinear crystals are the crystals that display non-linear optical effects above the second order of laser strong electric fields, and are one of the important photoelectric information functional materials. The wavelength expansion of the laser light source largely depends on the frequency conversion ability of the nonlinear optical crystal. It is the material basis and source for obtaining lasers of different wavelengths (different colors). It is widely used in laser storage, laser communication, laser medical treatment, semiconductor micro-processing, and optical communication, laser processing, holographic photography, laser fusion, laser weapons and other fields. Common nonlinear crystals include LiNbO3,
