摘要：
The interaction of a vortex and an edge phase dislocation nested in a Gaussian beam by its free space propagation is studied experimentally and theoretically in the paraxial regime. Ibis interaction induces the nucleation of additional vortices of both topological charges. Their positions and number depend on which of the phase dislocations is shifted from the center of the host beam. The interaction of noncoaxial light beams containing these phase dislocations is also reported.
