Abstract

The invention provides an Rb3Al3B3O10F compound, Rb3Al3B3O10F nonlinear optical crystals as well as a preparation method and use thereof and relates to the field of non-linear optical crystal materials. The frequency-doubling conversion efficiency of the Rb3Al3B3O10F nonlinear optical crystals at 1064nm is about 1.2 times of that of the KH2PO4 (KDP) crystal, ultraviolet absorption cutoff edges of the Rb3Al3B3O10F nonlinear optical crystals are shorter than 200nm and the Rb3Al3B3O10F nonlinear optical crystals do not absorb moisture; the large-size transparent Rb3Al3B3O10F nonlinear optical crystals can separately grow by a fluxing agent method and adopting RbF-B2O3 as a fluxing agent; and the Rb3Al3B3O10F crystals have stable physical and chemical properties and moderate hardness and are easy to cut, process, store and use and can be used for preparing non-linear optical devices so as to explore nonlinear optical applications of ultraviolet and deep-ultraviolet bands.
