摘要:

我们观察到形成的强烈的光波包完全本地化在所有的维度,即纵向(在时间上)和横向平面中,具有几十个fsec和微米的延伸,分别。我们的测量结果表明,自陷波是一个X形的光子弹从一个标准的激光波包通过非线性材料响应(即,二次谐波产生),将孤子的概念扩展到一个新的领域,即主峰与反映线性色散关系对称性的锥尾共存。

英文摘要:

We observe the formation of an intense optical wavepacket fully localized in all dimensions, i.e. both longitudinally (in time) and in the transverse plane, with an extension of a few tens of fsec and microns, respectively. Our measurements show that the self-trapped wave is a X-shaped light bullet spontaneously generated from a standard laser wavepacket via the nonlinear material response (i.e., second-harmonic generation), which extend the soliton concept to a new realm, where the main hump coexists with conical tails which reflect the symmetry of linear dispersion relationship.
