technical field [0001] The present invention relates to a K 3 Ba 3 Li 2 Al 4 B 6 o 20 F compound, K 3 Ba 3 Li 2 Al 4 B 6 o 20 F nonlinear optical crystal, K 3 Ba 3 Li 2 Al 4 B 6 o 20 F crystal preparation method and K 3 Ba 3 Li 2 Al 4 B 6 o 20 F crystals are used to make nonlinear optical devices. technical background [0002] 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. The all-solid-state laser using nonlinear optical crystals for frequency conversion is a development direction of lasers in the fut...
