Abstract: The present invention relates to an orthogonal-phase compound and its nonlinear optical (NLO) crystal of BaGa7Se7, its producing method and uses thereof. Polycrystalline orthogonal-phase BaGa4Se7 was prepared by a high-temperature solid-phase reaction in a sealed silica tube. Large size single crystals of orthogonal-phase BaGa4Se7 could be prepared by the flux method or Bridgman method. BaGa4Se7 crystallizes in the point group mm2. Orthogonal-phase BaGa4Se7 has a powder second harmonic generation (SHG) efficiency of about 5 times that of AgGaS2 and is phase-matchable. The orthogonal-phase BaGa4Se7 is non-hygroscopic and has good mechanical properties, which makes it easy to cut, polish, and coat by normal processing. The orthogonal-phase BaGa4Se7 crystal has never been cracked during cutting and polishing. The orthogonal-phase compound and NLO crystal of BaGa4Se7 can be used as NLO devices.
