Description

technical field [0001] The invention relates to a compound cesium fluoroborate CsB 4 o 6 F and cesium fluoroborate CsB 4 o 6 F nonlinear optical crystal and its preparation method and application. Background technique [0002] As an important part of all-solid-state lasers, nonlinear optical crystals have been widely concerned by scholars at home and abroad. After half a century of research, a series of nonlinear optical crystals with excellent performance have been discovered. The representative nonlinear optical crystal in the visible light band is KTiOPO 4 (KTP), KH 2 PO 4 (KDP) and so on. In the ultraviolet band, the nonlinear optical crystal LiB that has been industrialized 3 o 5 (LBO), CsB 3 o 5 (CBO), CsLiB 6 o 10 (CLBO) and BaB 2 o 4 (BBO) etc. But in the deep ultraviolet band below 200nm, the practical nonlinear optical crystal is only KBe 2 BO 3 f 2 (KBBF). Due to the long growth period of the crystal, the presence of highly toxic Be elements, a...
