We investigated surface dark solitons (SDSs) at the interface between a self-defocusing nonlocal nonlinear medium and a linear medium, both theoretically and experimentally. We demonstrate that fundamental and higher-order SDSs can exist when the linear refractive index of the self-defocusing medium is much greater than that of the linear medium. The fundamental and second-order solitons are observed at the interface between air and a weakly absorbing liquid.
我们从理论和实验两方面研究了自散焦非局域非线性介质与线性介质界面处的表面暗孤子（SDSs）。我们证明，当自散焦介质的线性折射率远大于线性介质的线性折射率时，基阶和高阶表面暗孤子能够存在。在空气与弱吸收液体的界面处观测到了基阶和二阶孤子。
