ABSTRACT:
The present invention relates to nonlinear optical crystals of compound Na3La9B8O27and producing method and uses thereof. From the Na3La9B8O27compound, large size single crystal of Na3La9B8O27could be prepared by flux method. Na3La9B8O27crystals 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.
