We present a class of partially coherent light sources having Airy-type amplitude and Airy-correlated spatial coherence. We show that the light beam generated by such sources can preserve the Airy beam pattern well during its propagation from source to far field. We demonstrate the robustness of the Airy beam pattern by introducing a hard aperture to largely block the beam source. We find that the coherence-induced Airy beam pattern can still be well reconstructed during propagation. We successfully synthesize such partially coherent source using the principle of complex random modes decomposition by using a single phase-only spatial light modulator. The proposed robust Airy beam pattern may find applications in information transmission through complex media.
我们提出了一类具有艾里型振幅和艾里相关空间相干性的部分相干光源。我们表明，由此类光源产生的光束在从光源传播到远场的过程中能够很好地保持艾里光束模式。我们通过引入一个硬孔径来大幅阻挡光束源，以此证明了艾里光束模式的稳健性。我们发现，在传播过程中相干诱导的艾里光束模式仍然能够很好地重构。我们利用复随机模式分解原理，通过使用单个纯相位空间光调制器成功合成了这种部分相干光源。所提出的稳健艾里光束模式可能在通过复杂介质的信息传输中找到应用。
