Abstract
A preparation method and application of a NaBa(BO)F birefringent crystal, the crystal having a chemical formula of NaBa(BO)F, and belonging to a hexagonal crystal system, the space group being P6/m, and the lattice parameters comprising a=7.3490(6) Å, c=12.6340(2) Å, V=590.93(12) Å, Z=2; the crystal is used for an infrared/deep ultraviolet waveband, and is an uniaxial negative crystal, n<n, the transmission range being 175-3,350 nm, the birefringence of 0.090 (3,350 nm)-0.240 (175 nm), and the crystal being grown by employing a melting method or a flux method; the crystal prepared via the method has a short growth cycle, high crystal quality and large crystal size, is easy to grow, cut, polish and store, is stable in the air, and difficult to deliquesce, and can be used for preparation of various polarization beam polarization beam splitter prism and infrared/deep ultraviolet waveband optical communication elements.
