摘　　要：在钛扩散LiNbO_3平面光波导中,用端面耦合方法实现了相向传播光脉冲的非简并四波混频效应。实验发现,倍频光以一定的发散角沿垂直于波导表面的方向传播,而发散的机理可用夫琅和费衍射理论解释。:The experiment of nondegenorato four-wave mixing was carried out in Ti-diffu-sed LiNbO3 single mode waveguide:by end-face coupling. The frequency doubled light propagated certain divergent angle in the direction perpendicular to the surface was observed. The mechanism of divergence was explained by the theory of diffraction.
