Abstract

We generate experimentally optical ring lattice structures which are the superposition of two coaxial Laguerre–Gaussian modes with common waist position and waist parameter. Although these structures are not dif fraction-free, they show self-healing property. This self-reconstruction of the ring lattice can be understood by looking into the transverse energy flow at different z planes. The experimental results are verified by the numerical simulations.
