  • Nonlinear optical crystals of compound Na3La9B8O27 and producing method and uses thereof
    Patent number: 6921498
    Abstract: The present invention relates to nonlinear optical crystals of compound Na3La9B8O27 and producing method and uses thereof. From the Na3La9B8O27 compound, large size single crystal of Na3La9B8O27 could be prepared by flux method. Na3La9B8O27 crystals are non-hygroscopic, and possess stronger nonlinear optical effect and good mechanical properties. They meet the requirements for the frequency conversion of blue—green wavelength lasers and could be used to prepare nonlinear optical devices.

  • Nonlinear optical crystal of compound R.sub.2 MB.sub.10 O.sub.19 and producing method and producing method and uses thereof
    Patent number: 6146553
    Abstract: The present invention provides a compound having the chemical formula of R.sub.2 MB.sub.10 O.sub.19, wherein R is one or more elements selected from the group consisting of rare-earth elements or Y; M is selected from the group consisting of Ca, Sr, Ba, a single crystal of the compound, a producing method and uses thereof. The compound is congruently melting, which is suitable for producing large size single crystal of R.sub.2 MB.sub.10 O.sub.19 with melt methods, especially pulling method, at a low cost. The crystal resulted therefrom has the same NLO effect as LBO with superior mechanical properties, and it is antideliquenscent. The crystal of the present invention can be used for the frequency-conversion of blue-green wavelength lasers.
