Abstract.
In this work, we report numerical simulations and experimental results indicating the possibility of determining and controlling the rate of change of the Gouy phase of structured Gaussian-like beams. This is achieved by nesting singly-charged optical vortices with the same signs of their topological charges in necklace-like structures.
