Abstract

We show the dynamics of evolution of screw phase-dislocations existing in the wave front of Gaussian beam with nested multiple-charged vortices that propagate in quadratic nonlinear crystals under conditions for seeded second-harmonic generation. The number of existing vortices is shown to depend on the input light and material conditions, including the topological charge, width and intensity of the pump and seed signals, as well as on the propagation length inside the crystal.
