介绍了具有轨道角动量的空间光孤子的研究进展,包括两个方面的内容:具有轨道角动量的椭圆形光束可以在各向同性介质中以孤子状态稳定传输;具有轨道角动量的光强旋转型孤子在传输材料、光束模式和光束起转方式方面的研究进展。
The study on the spatial optical solitons with orbital angular momentum is introduced, which includes two contents:the elliptic beams with orbital angular momentum can propagate in the isotropic medium as a soliton; the rotating spatial solitons are studied in the transporting medium, optical mode and the rotating method.
