The useful nonlinear coefficients of Ba2NaNb5O15 are approximately twice those of LiNbO3. This material is a filled (A sites) structure composition and at room temperature does not have the serious problem of optically induced refractive index inhomogeneities (``optical damage''). Also, the material has unique and reproducible phasematch temperatures. The electro-optic half-wave voltage of this material in the optimum direction is 1570 V.
