摘要:

我们揭示了衍射、立方非线性、双光子吸收和时空局域增益之间的竞争导致了时空波包坍缩的停止、方位调制不稳定性的抑制和稳定的三维光弹的形成。我们发现,高斯时空增益景观支持明亮的,基本的光子弹,而具有环状空间和高斯时间形状的增益景观可以支持稳定的旋涡子弹携带拓扑相位位错。

英文摘要:

We reveal that the competition between diffraction, cubic nonlinearity, two-photon absorption, and gain localized in both space and time results in arrest of collapse, suppression of azimuthal modula-tion instabilities for spatiotemporal wavepackets, and formation of stable three-dimensional light bul-lets. We show that Gaussian spatiotemporal gain landscapes support bright, fundamental light bullets, while gain landscapes featuring a ring-like spatial and a Gaussian temporal shapes may support stable vortex bullets carrying topological phase dislocations.
