光波turbulence与光的凝聚

Optical wave turbulence and condensation of light

Umberto Bortolozzo, Jason Laurie, Sergey Nazarenko, Stefania Residori

摘要:

在一个光学实验中,我们报告了一个波湍流制度,开始与弱非线性波随机相位,显示了反向级联的光子对最低波数。我们表明,级联是由一个六波共振相互作用过程,其特点是增加非线性。在低波数下,非线性变强,导致调制不稳定性发展成孤子,其数量沿光束进一步减少。

英文摘要:

In an optical experiment, we report a wave turbulence regime that, starting with weakly nonlinear waves with randomized phases, shows an inverse cascade of photons towards the lowest wavenumbers. We show that the cascade is induced by a six-wave resonant interaction process and is characterized by increasing nonlinearity. At low wavenumbers the nonlinearity becomes strong and leads to modulational instability developing into solitons, whose number is decreasing further along the beam.
