Abstract

在这篇评论文章,我们总结了在红宝石与组速度变化联系的弱轻非线性的性质的学习。红宝石能被归结为一个二水平的系统,在人口,摆动能导致 subluminal 结果。与介绍进红宝石的调制 TEM00 横梁,和 Fraunhofer 衍射和 nondegenerate 的自我阶段调整在横梁的不同空间频率部件之间的二波浪的联合同时发生。人口摆动,和 Fraunhofer 衍射和 nondegenerate 的自我阶段调整二波浪的联合机制与对方竞争,它在红宝石带 self-superluminal 组速度繁殖的新现象。

Nonlinear optical properties and superluminal propagation in the ruby

Jing Xu

In this review article,we summarized the study of the weak light nonlinear properties associated with group velocity change in the ruby.The ruby could be reduced to a two-level system,in which population oscillations could lead to a subluminal result.With the modulated TEM00 beam introduced into the ruby,self-phase modulation together with Fraunhofer diffractions and nondegenerate two-wave coupling between different spatial frequency components of the beam occurs at the same time.Population oscillations,self-phase modulation together with Fraunhofer diffractions and nondegenerate two-wave coupling mechanism competes with each other,which brings a new phenomenon of self-superluminal group velocity propagation in the ruby.
