Investigating the self-healing property of an optical Airy beam

We report the theoretical and experimental study of the self-healing property of an Airy beam related to its phase. We find that, even when the phase of an Airy beam is not preserved, the beam still exhibits the self-healing property but undergoes a severe diffraction. To decrease the diffraction effect, we utilize an electromagnetically induced transparency (EIT) image-cloning system based on position selective absorption effect to further demonstrate the self-healing phenomenon. Our experimental results show excellent agreement with the theoretical analysis.
