高斯谢尔模型光束非镜面效应的观测

Observation of nonspecular effects for Gaussian Schell-model light beams

Michele Merano, Gabriele Umbriaco, Giampaolo Mistura

摘要:

实验研究了空间相干性对光束位移的影响。这一主题是最近理论辩论的主题。本文考虑高斯-谢尔模型光束,具有不同的空间相干度,在空气-玻璃界面上反射。我们证明了入射光束的空间相干度对角Goos-Hänchen效应和角Imbert-Fedorov效应有影响,而空间Goos-Hänchen效应不依赖于非相干性。我们的数据毫不含糊地解决了有利于一个特定理论的理论辩论。

英文摘要:

We investigate experimentally the role of spatial coherence on optical beam shifts. This topic has been the subject of recent theoretical debate. We consider Gaussian Schell-model beams, with different spatial degrees of coherence, reflected at an air-glass interface. We prove that the angular Goos-Hänchen and the angular Imbert-Fedorov effects are affected by the spatial degree of coherence of the incident beam, whereas the spatial Goos-Hänchen effect does not depend on incoherence. Our data unambiguously resolve the theoretical debate in favour of one specific theory.
