Nonlinear optical crystal of compound R.sub.2 MB.sub.10 O.sub.19 and producing method and producing method and uses thereof
 The present invention provides a compound having the chemical formula of R.sub.2 MB.sub.10 O.sub.19, wherein R is one or more elements selected from the group consisting of rare-earth elements or Y; M is selected from the group consisting of Ca, Sr, Ba, a single crystal of the compound, a producing method and uses thereof. The compound is congruently melting, which is suitable for producing large size single crystal of R.sub.2 MB.sub.10 O.sub.19 with melt methods, especially pulling method, at a low cost. The crystal resulted therefrom has the same NLO effect as LBO with superior mechanical properties, and it is antideliquenscent. The crystal of the present invention can be used for the frequency-conversion of blue-green wavelength lasers.
