我们提出了在强调波传播固有的时空和多维性质的条件下二次介质横向不稳定性的实验和数值观察。强度相关的光束成丝被证明与二次孤子的周期性演化密切相关，并讨论了对三维时空孤子生成的影响。
We present experimental and numerical observations of transverse instability in quadratic media under conditions that emphasize the inherently spatiotemporal and multidimensional nature of the wave propagation. Intensity-dependent beam filamentation is shown to be closely connected to the periodic evolution of quadratic solitons, and implications for the generation of three-dimensional spatiotemporal solitons are discussed.
