Description

technical field [0001] The present invention relates to a kind of Cs 3 C 6 N 9 ·H 2 O compound, Cs 3 C 6 N 9 ·H 2 O nonlinear optical crystals and Cs 3 C 6 N 9 ·H 2 O crystals are used in the manufacture of nonlinear optical devices. [0002] technical background [0003] The nonlinear optical effect of crystal refers to such an effect: when a beam of laser light with a certain polarization direction passes through a nonlinear optical crystal in a certain direction, the frequency of the beam will change. Crystals with nonlinear optical effects are called nonlinear optical crystals. Using the nonlinear optical effect of crystals, nonlinear optical devices such as second harmonic generators, up-down frequency converters, and optical parametric oscillators can be made. All-solid-state lasers using nonlinear optical crystals for frequency conversion are a development direction for future lasers, and the key lies in obtaining excellent nonlinear optical crystals.
