对两艾里-高斯光束在一维非局域非线性缺陷晶格中的相互作用进行数值研究,并分别讨论了非线性非局域性、晶格性质、光束性质、光束入射角以及两光束相位差对传输实验结果的影响。实验发现两艾里-高斯光束在不同条件下相互作用会形成晶格孤子、准呼吸子,甚至还出现了晶格孤子对。其中,多数情况下观察到了准呼吸子,且准呼吸子的空间大小和周期受到了非局域非线性、晶格缺陷以及光速自加速的影响。当两艾里-高斯光束之间存在相位差入射时,它们在晶格中相互作用,形成两个孤子对,一对孤子垂直传输,而另一对孤子斜向传输。

Interaction of two Airy-Gaussian beams in a one-dimensional nonlocal nonlinear defected lattice is numerically studied, and the effects of the nonlinear non-local properties, lattice properties, beam properties, beam incidence angle, and phase difference between the two beams on the experimental results are discussed. It is found that the interaction of two Airy-Gaussian beams under different conditions forms lattice solitons, quasi-breaths, and even lattice solitons. In most cases, the quasi-breaths are observed, and their spatial size and period are affected by nonlocal nonlinearity, lattice defects, and light self-acceleration. When phase difference exists between the two incident Airy-Gaussian beams, the interaction in the lattice will form a soliton pair, with one soliton transmitting vertically and the other soliton transmitting diagonally.
