我们证明，超长拉曼激光器可以用来产生一个传输介质，同时在空间和光谱域的透明度。数值计算表明，这种跨域透明被保存时，该介质用于传输高强度信号，这使得超长激光器的一个理想的实验测试平台，用于研究光纤波导中的多频非线性相互作用。在20 nm x 20 km窗口上通过实验获得了完全的空间光谱透明性。
We demonstrate that ultralong Raman lasers can be used to generate a transmission medium with simultaneous transparency over the spatial and the spectral domains. Numerical calculations show this cross-domain transparency to be preserved when the medium is used for transmitting high-intensity signals, which makes ultralong lasers an ideal experimental test bed for the study of multifrequency nonlinear interactions in optical fiber waveguides. Full spatiospectral transparency is experimentally obtained over a 20 nm x 20 km window.
