Description

technical field [0001] The invention relates to a compound rubidium boron nitrate and a nonlinear optical crystal of rubidium boron nitrate, a preparation method and an application. Background technique [0002] The wide application of laser technology has made people have great interest in the research and development and application of laser technology. At present, the direct output bands of lasers are limited, and there are still gaps in many bands, which are far from meeting the development and needs of the industry. The use of new nonlinear optical crystals can effectively expand the output wavelength range of lasers to effectively open up laser light sources. At present, some nonlinear optical crystals with relatively good comprehensive performance have been widely used in frequency conversion, optical frequency comb, information communication and other fields, such as LiB 3 o 5 (LBO), β-BaB 2 o 4 (BBO), KH 2 PO 4 (KDP), and KTiOPO 4 (KTP). [0003] However, t...
