摘　　要：We theoretically demonstrate that Kerr media under self-focusing nonlinearity support three-dimensional spatiotemporal solitary waves in various patterns,such as necklace-,disk-,and vortex-ring shapes.The structures of these solitons are defined by the set of radial,orbital,and azimuthal quantum numbers,(n,l,m),respectively.
