实验研究了远场边界条件对局域光束演化有显著影响的非局域光学非线性介质中的波传播。作为例子，我们将边界条件设置为各向异性，并首次实验观察到相干椭圆孤子。此外，利用这种非线性的自然能力来消除方位不稳定性，我们首次观测到了稳定的涡环孤子。受远距离边界条件影响的高度非局域非线性的这些特性，为实现对孤子传播的远程控制开辟了非线性科学的新方向。
We present an experimental study on wave propagation in highly nonlocal optically nonlinear media, for which far-away boundary conditions significantly affect the evolution of localized beams. As an example, we set the boundary conditions to be anisotropic and demonstrate the first experimental observation of coherent elliptic solitons. Furthermore, exploiting the natural ability of such nonlinearities to eliminate azimuthal instabilities, we perform the first observation of stable vortex-ring solitons. These features of highly nonlocal nonlinearities affected by far-away boundary conditions open new directions in nonlinear science by facilitating remote control over soliton propagation.
