Abstract
The invention relates to a lithium metaborate crystal and a preparation method and use thereof. The crystal has a chemical formula of LiBO, a molecular weight of 49.75, and is a member of the monoclinic crystal system. The crystal has a P2/c space group and lattice constants of a=5.85(8) Å, b=4.35(7) Å, c=6.46(6) Å, β=115(5)°, and Z=4. The crystal can be applied in wavelengths of infrared-visible-deep ultraviolet, and is grown by utilizing a melt crystallization method or a flux method. The crystal obtained using the method described in the invention is easily grown and processed, and can be used in the manufacture of a polarizing beam splitting prism such as a Glan prism, a Wollaston prism, a Rochon prism or a beam-splitting polarizer, and other optical components, enabling crucial applications in the fields of optics and communication.
