Research on Self-healing Properties of Finite Energy Airy Beams

对有限能量Airy光束的自我修复特性做了深入研究，给出了畸变有限能量Airy光束的自我修复能力是弱衍射光束与衍射光束的竞争机制新的理论说明。文中采用对比实验、结合数值模拟得到自由传播下不同初始畸变的有限能量Airy光束的场分布演变过程，结果表明：初始光束的主瓣畸变是一个渐近修复过程，畸变越大修复速度越快；而初始光束的旁瓣畸变是一个光束能量波动修复过程，离主瓣越远的旁瓣被遮挡自我修复速度越快。
： The self-healing properties of finite energy Airy beams were discussed in detail, A theory of weak-diffraction beam and diffraction beam competition was put forword to explain the self-healing propagation of finite energy Airy beams. In this paper, the field evolutions of finite energy Airy beams with different initial distortions under free propagation were obtained by numerical simulation and comparative experiment.The result showed that the beams propagation with the initial main lobe distortion would be an asymptotic repair process. The greater the distortion was, the faster the restoration would be.While the beams propagation with the initial sidelobe distortion would be a repair process of energy fluctuation. The further the sidelobe blocked from the main lobe were, The more quickly the sidelobe repaired
