Synthesis of astigmatic non-uniformly correlated beams

We present a general strategy for synthesizing astigmatic random structured light beams by jointly manipulating the astigmatic phase and optical coherence. With it, we facilitate the creation of a distinct category of beams termed astigmatic non-uniformly correlated (ANUC) beams. Our study emphasizes the significant influence of the astigmatic phase on the optical spatial coherence distribution, resulting in novel propagation features. Furthermore, we elucidate their underlying physical nature. Experimentally, we successfully generate such beams, validating theoretical projections. Our findings hold promise for diverse applications requiring adaptable spectral density control.
