摘要
在LiNbO_3:Fe晶体中双光束对称入射几何配置下观察到由共享光栅对多种各向异性散射光锥的增强(5—10倍),提出了由两组三波、四波混合共享光栅的六波、八波混合理论模型.理论计算与实验结果符合很好.
The enhancement of the intensity of anisotropic scattering cones has been observed by the geometry in which two beams are incidented symmetrily on a LiNbO3:Fe crystal sheet. We proposed a model of six-wave and eight-wave mixing from two groups of three-wave and four-wave mixing which shared grating each other. The experimental results agree well with the theoretical analysis.
