说明书摘要	The present invention relates to a potassium chloroborate nonlinear optical crystal, a preparation method and a use thereof. The crystal has a chemical formula of K3B6O10Cl, has no symmetric center, belongs to rhombohedral crystal system, has a space group R3m with unit cell parameters of a=10.0624(14)?, b=10.0624(14)?, c=8.8361(18)?, Z=3 and V=774.8(2)?3. It has a powder second harmonic generation efficiency of about 3 times that of KDP (KH2PO4), and a Mohs hardness of 4-5, a transparent wavelength range of 165 nm-3460 nm. The compound is synthesized by a solid-state reaction and the crystal is grown by using a flux, which are of easy operation and low costs. The obtained crystal has large size, short growing period, little inclusion, relatively high mechanical hardness, and is easy to be cut, polished and stored. Said crystal is used to generate a second, third, fourth or fifth harmonic light output for a laser beam with a wavelength of 1064 nm.
