Abstract

The invention relates to a Na3M2(BO3)3 nonlinear optical crystal as well as a preparation method and an application. The Na3M2(BO3)3 nonlinear optical crystal does not have the symmetric center and belongs to the orthorhombic system, and the space group is Amm2. Crystals are grown by a flux growth method, Na3M2(BO3)3, Na2CO3 and H3BO3 are prepared according to the mol ratio of 1 : (1-5) : (1-5) and then are put in a muffle furnace for heating and fusing; and then the fused materials are put in a single-crystal growth furnace, and the crystals are grown by a seed crystal method. The Na3M2(BO3)3 nonlinear optical crystal has the nonlinear optical effect with the size of one to three times of KDP(KH2PO4) and good machining property, is not easy to deliquesce and suitable for meeting the requirements on laser frequency conversion of blue and green optical bands, and can be used for preparing nonlinear optical elements; in addition, when an M part is replaced by rare-earth active ions, the single crystal can be used for preparing laser nonlinear optical compound functional devices.
