Description

technical field

[0001] The invention relates to a compound rubidium boron nitrate and rubidium boron nitrate nonlinear optical crystal, a preparation method and application thereof. Background technique

[0002] The wide application of laser technology makes people have great interest in the research and development and application of laser technology. At present, the direct output band of lasers is limited, and there are still gaps in many bands, which are far from meeting the development and needs of the industry. Using the new nonlinear optical crystal, the output wavelength range of the laser can be effectively expanded to effectively open up the laser light source. At present, some nonlinear optical crystals with excellent comprehensive properties 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).
