我们观察了光折变晶体中三孤子碰撞后以不稳定能量传递和孤子湮灭和产生为特征的混沌光波动力学。发现不规则动力学是由非线性拉曼效应介导的，这是一种导致非互反孤子能量交换的相干相互作用。结果将孤子和粒子之间的类比扩展到三体物理中混沌的出现，并为伴随极端和异常波的不规则动力学的起源提供了新的见解。
We observe chaotic optical wave dynamics characterized by erratic energy transfer and soliton annihilation and creation in the aftermath of a three-soliton collision in a photorefractive crystal. Irregular dynamics are found to be mediated by the nonlinear Raman effect, a coherent interaction that leads to nonreciprocal soliton energy exchange. Results extend the analogy between solitons and particles to the emergence of chaos in three-body physics and provide new insight into the origin of the irregular dynamics that accompany extreme and rogue waves.
