本文研究了强非局域介质中简谐势的精确解析解。用自相似方法得到了二维贝塞尔孤波团。详细讨论了不同参数下的光束强度分布。发现孤立波具有对称的项链分布,光斑点数是量子数m的两倍。讨论了外势场对光束宽度的调制作用。
An exact analytical solution in strongly non-local media with a harmonic potential has been studied. Two-dimensional Bessel solitary wave clusters have been obtained by a self-similar method. The intensity distributions of optical beam with different parameters have been discussed in detail. It is found that the solitary waves have a symmetric necklace distribution and the number of facular points is double the value of the quantum numberm. The modulation of the external potential field to the width of light beam is also discussed.
