摘要: The perfect hybrid vector vortex beam (PHVVB) with helical phase wavefront structure has aroused significant concern in recent years, as its beam waist does not expand with the topological charge (TC). In this work, we investigate the spatial quantum coherent modulation effect with PHVVB based on the atomic medium, and we observe the absorption characteristic of the PHVVB with different TCs under variant magnetic fields. We find that the transmission spectrum linewidth of PHVVB can be effectively maintained regardless of the TC. Still, the width of transmission peaks increases slightly as the beam size expands in hot atomic vapor. This distinctive quantum coherence phenomenon, demonstrated by the interaction of an atomic medium with a hybrid vector-structured beam, might be anticipated to open up new opportunities for quantum coherence modulation and accurate magnetic field measurement.
