Abstract

The invention provides a compound rubidium borofluoride and a rubidium borofluoride non-linear optical crystal and a preparation method and use of the rubidium borofluoride non-linear optical crystal. The compound rubidium borofluoride has a chemical formula of RbB4O6F, has molecular weight of 243.71 and is prepared through a solid phase synthesis method or a vacuum packaging method. The crystal has a chemical formula of RbB4O6F, has molecular weight of 243.71, belongs to the orthorhombic system, and has a space group of Pna 21 and cell parameters such as a=7.6742A, b=11.228A, c=6.6218A, alpha=beta=gamma=90 degrees, unit-cell volume of 570.57 A<3>, crystal frequency-doubled effect about 1.9 times that of KH2PO4 (KDP) and ultraviolet absorption edge shorter than 190nm. The crystal is formed through a melt method, a high temperature melt method, a vacuum encapsulation method, a hydrothermal method or a room-temperature solution method. The crystal has good chemical stability and can be used as an ultraviolet and deep-ultraviolet non-linear optical crystal in an all-solid-state laser.

Description

technical field [0001] The invention relates to a compound rubidium fluoroborate RbB 4 o 6 F and rubidium fluoroborate RbB 4 o 6 F nonlinear optical crystal and its preparation method and application. Background technique [0002] Deep ultraviolet nonlinear optical crystals can use their frequency conversion properties to convert near-infrared and visible lasers into deep ultraviolet lasers with wavelengths less than 200nm, and have important application values ​​in medical, communication, scientific research and other fields. As we all know, the only practical deep ultraviolet nonlinear optical crystal is the KBe invented by Chinese scientists. 2 BO 3 f 2 (KBBF) crystal, which has a layered growth habit, and it is difficult to grow large-sized crystals, which limits its application to a certain extent. Therefore, it is of great significance and practical value to prepare and synthesize new deep ultraviolet nonlinear optical crystal materials with excellent comprehens...
