摘要
The present invention relates to a new type NLO crystal Strontium Beryllatoborate (Chemical formula Sr2Be2B2O7, abbr. SBBO). The SBBO compound is synthesized by chemical reaction of solid state in high temperature sintering, Its chemical reaction equation is: 2SrCO3+2BeO+2H3BO3->Sr2Be2B2O7+2CO2 +3H2O A flux method is applied to the growth of single crystal of Strontium Beryllatoborate, in which SrB2O4, NaF and other fluorides were used as flux solvents. The result of measurement indicated that this compound has following structural and physical characteristics: space group: P63(C66) point group: C 6, unit cell: a=4.663(3) ANGSTROM , c=15.311(7) ANGSTROM ,z=2, V=283.3( ANGSTROM )3. SBBO belongs to crystal of negative optical axis, its harmonic generation devices, optical parameter and amplifier devices and optic-wave guide devices in UV region will win wide application, the coherent light of wave length shorter than 200 nm can be produced through direct frequency-multiplication.
