Abstract

We study the first experimental collisions of two incoherent self-focused counterpropagating Airy beams in a nonlinear crystal. Their interactions demonstrate that the self-focusing dynamics of the Airy beams can be spatially controlled by the counterpropagating Airy beam. By tuning the misalignment and the size of the beams, we can control the output position of the self-focused Airy beam and switch to multiple outputs. Also the nonlinearity strength enables to engineer the temporal stability of the resulting waveguide structure.

摘要

我们研究了两个非相干自聚焦反向传播艾里光束在非线性晶体中的首次实验碰撞。它们的相互作用表明，艾里光束的自聚焦动力学可以通过反向传播的艾里光束在空间上进行控制。通过调整光束的错位和尺寸，我们可以控制自聚焦艾里光束的输出位置并切换到多个输出。此外，非线性强度能够设计所得波导结构的时间稳定性。
