摘要
实验研究了在掺铁锂酸铌晶体中由外部微小噪音引起的调制失稳和外部周期调制引起的调制失稳。并详细研究了光束细丝方向与c轴之间的夹角对晶体中调制失稳的影响。另外，分别研究了外部周期格子的主轴与晶体c轴平行时和呈45°角时晶体中的调制失稳的影响。
We investigated experimentally the modulation instability generated by external tiny noise andexternal periodic modulation in Lithium niobate crystal.We discussed the influences on the modulation instability inthe crystal in detail,which was generated by the angle between beam filament and the crystalline c -axis.Inaddition,the influences on the modulation were studied when the angle between the spindle of external periodiclattice and the crystalline c -axis were 0°and 45°respectively.
