Description

[0001] Technical field

[0002] The invention relates to an inorganic crystal compound and a preparation method and application thereof, and belongs to the field of inorganic chemistry, as well as the field of materials science and optics. Background technique

[0003] The nonlinear optical effect originates from the interaction between the laser and the medium. When the laser propagates in a medium with a non-zero second-order polarizability, it will produce nonlinear optical effects such as frequency doubling, sum frequency, difference frequency, and optical parametric amplification. Using the second-order nonlinear optical effect of crystals, nonlinear optical devices such as second harmonic generators, frequency converters, and optical parametric oscillators can be made, which are important in many fields such as laser technology, atmospheric monitoring, and national defense. Application value. Inorganic nonlinear optical materials play a leading role in the practical resear...
