摘要
本文从理论上证明,由于各种表面效应和光在焦点处的特殊性质及径向梯度介质的本征非线性作用,凡经聚焦而进入径向梯度介质的细光束,均会产生稳态半自陷而保径传播。这为开辟该介质的应用提供了新的理论根据。
In this paper, it is proved that the stable half-self traped phenomenon can be generated, and beamlet can be propagated with the identically diameter since the surface effects and the specific nature of light in focus as well as the action of intrinsic nonlinearity in radial gradient media.. A new theorical base is provided to open up applications of these media
