将联合收割机非中心对称性、大的二阶非线性光学（NLO）极化率、深紫外透明性和相位匹配性同时结合到单一结构中是一个巨大的挑战。特别是宏观相匹配性与微观结构之间的关系研究较少。在此，我们报道了一种独特的Ba_2NaClP_2O_7，它代表了fresnoite家族的第一个相位匹配的例子，它表现出优异的非线性光学特性，包括短吸收边（
To combine noncentrosymmetry, large second order nonlinear optical (NLO) susceptibility, deep UV transparency, and phase matchability simultaneously into a single structure is a great challenge. Especially, the relationship between the macrophase matchability and microstructure has been less investigated. Herein, we report a unique Ba2NaClP2O7 representing the first phase-matchable example of the fresnoite family, which exhibits excellent NLO properties, including short absorption edge (
