Abstract
The present invention provides a barium fluoroborate compound, a nonlinear optical crystal and the preparation method and use thereof. Both of the barium fluoroborate compound and the nonlinear optical crystal have a chemical formula of BaBOF. The crystal belongs to orthorhombic crystal system, has a space group Cmc2with unit cell parameters of a=18.802(3) Å, b=10.7143(19) Å, c=8.6113(14) Å, V=1734.7(5) Å. The crystal has a powder second harmonic generation efficiency of 10 times that of KDP (KHPO). The ultraviolet cutoff wavelength is about 170 nm. The barium fluoroborate compound is prepared by a solid-state reaction. The barium fluoroborate nonlinear optical crystal prepared by a high temperature melting liquid method has large hardness and is easy to be cut, polished and stored. This crystal can be used widely in preparing the nonlinear optical devices of the second harmonic generator, the up frequency converter, the down frequency converter or the optical parametric oscillator or the like.
