摘要：

Methods are described for generating vortices that are exact solutions of the paraxial wave equation that have arbitrary Poincare-Hopf indices (positive, negative, or zero), and arbitrary topological charges (winding numbers). Vortices with indices greater than I are decorated with phase "petals", and take the form of vortex flowers. Instructions are provided for sowing flower gardens, and decay modes under propagation of flowers implanted in Gaussian laser beams are studied. (C) 2001 Elsevier Science B.V. All rights reserved.
