摘要

从理论上证明了在没有二阶谐波色散的情况下，在二次谐波产生模式下出现具有正常群速度色散在基频的光-暗时空孤子的可能性。这个物体在时间和传播方向的坐标上具有暗色双色孤子的形式，在横向（空间）坐标上具有光的形式。

Parametric Light–Dark Spatiotemporal Soliton

The possibility of the appearance of a light–dark spatiotemporal soliton in the second-harmonic generation mode with the normal group velocity dispersion at the fundamental frequency in the absence of such a dispersion at the second harmonic frequency has been demonstrated theoretically. This object has the form of a dark two-color soliton with respect to time and coordinate in the direction of propagation and is light with respect to the transverse (spatial) coordinates.
