Problems solved by technology

And KBe 2 BO 3 f 2 (KBBF) The crystal layers are connected by the ionic bonds of K and F, and the bonding force between the layers is very weak. Because of this, it has a strong layered growth habit, and it is difficult for the crystal to grow thick and difficult. Processing, easy to dissociate, so it is difficult to put into practical use

Abstract

Provided are a deep ultraviolet non-linear optical crystal of barium borate hydrate, a preparation method therefor and the use thereof. The chemical formula of the crystal is Ba2B11O22H7, belonging to the monoclinic system, with the space group thereof being P2 1, the crystal cell parameters thereof being a = 6.7719(10)Å, b = 21.1195(4)Å, c = 6.8274(10)Å, β = 119.3950(10)°, and the molecular weight thereof being 752.65. The non-linear optical crystal of borate is obtained by means of programmed cooling or natural cooling using a hydrothermal method. The crystal powder has a frequency-doubling effect of about 2 times that of KDP(KH2PO4) and an ultraviolet cut-off edge of below 175 nm, and can be used as a deep ultraviolet non-linear optical crystal. The growth process of the crystal has advantages such as easy operation, a low cost, a low toxicity of raw materials, a short growth cycle, stable physical and chemical properties, etc. The deep ultraviolet non-linear optical crystal of barium borate hydrate Ba2B11O22H7 is widely used in the preparation of non-linear optical devices such as frequency doubling generators, upper frequency converters, lower frequency converters, optical parametric oscillators etc.
