摘要

采用数值模拟方法研究了在非中心对称介质中形成（2D + 1）短周期（包络线下振荡3-5次）轻弹的可能性。只有在一定强度下，三次非线性才能阻止时空孤子的形成。

Few-Cycle Two-Frequency Light Bullets with Phase and Group Velocity Detunings

Numerical modeling is used to show the possibility of forming (2D + 1) short-period (3‒5 oscillations under the envelope) light bullets in noncentrosymmetric media at the second harmonic generation with phase and group velocity detunings. Only up to certain intensities does cubic nonlinearity prevent the formation of space-time solitons.
