Description

Technical field [0001] The present invention relates to a Rb 3 Al 3 B 3 O 10 F nonlinear optical crystal and the Rb 3 Al 3 B 3 O 10 Preparation method of F crystal. [0002] technical background [0003] The nonlinear optical effect of the crystal refers to 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 and down frequency converters, and optical parametric oscillators can be made. All-solid-state lasers that use nonlinear optical crystals for frequency conversion are a development direction for future lasers, and the key is to obtain excellent nonlinear optical crystals. [0004] Currently, the nonlinear optical crystals used in the ultraviolet band mainly incl...
