We show that the weak second harmonic light generated from a random distribution of nonlinear domains of transparent Strontium Barium Niobate crystals can display a particularly intense generation in the forward direction. By using a theoretical model able to analyze the optical response of arbitrary distributions of three-dimensional nonlinear volumes of any shape, we found that the physical origin of this observation can be explained in terms of the scattering of light by a single nonlinear domain.
我们表明，由透明铌酸锶钡晶体的非线性域随机分布产生的弱二次谐波光可在正向显示出特别强烈的产生。通过使用一种理论模型，该模型能够分析任意形状的三维非线性体积的任意分布的光学响应，我们发现这一观测结果的物理起源可以用单个非线性域对光的散射来解释。
