Abstract

The invention relates to a nonlinear optical crystal Zn2(VO4)(IO3) and a preparation method and application thereof. The compound belongs to a monoclinic system; the space group of the compound is Pc, the crystal cell parameters of the compound are as follows: a=5,2714 (8), b=10.040 (1), c=5.5070 (8), beta=101.32 (1)<0>, Z=2, and the crystal cell volume V is 285.79 (7)<3>. The nonlinear optical crystal Zn2(VO4)(IO3) disclosed by the invention is prepared by adopting a hydrothermal method. The powder SHG (Second Harmonic Generation) coefficient of the compound Zn2(VO4)(IO3) is six times higher than that of KDP (KH2PO4).

Description

Technical field [0001] The invention relates to a new type of nonlinear optical crystal material. Background technique [0002] Non-linear optical crystals have a frequency doubling effect (SHG), and have important applications in high-tech fields such as laser frequency conversion, electro-optic modulation, and photorefractive information processing. Non-linear optical crystal materials are used in modern science and technology, especially in a number of military and civilian high-tech fields, such as submarine deepwater communications, laser blinding weapons, ocean fish detection, CD recording, color laser printing, laser projection television, optical computing And optical fiber communication, etc., have a series of important applications. The nonlinear optical crystals currently in practical use include α-LiIO 3 , KH 2 PO 4 (KDP), KTiOPO 4 (KTP), LiB 3 O 5 (LBO), β-BaB 2 O 4 (BBO), LiNbO 3 (LNO) and BaTiO 3 (BTO) etc. With the development of laser technology and the emerge...
