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.
