| 英文摘要 | Double-ring perfect vortex beams (DR-PVBs) have attracted increasing attention due to their unique characteristics of carrying independent information channels and exhibiting higher security and stability during propagation. In this study, we theoretically simulated and experimentally generated DR-PVBs with various topological charges. We investigated the propagation characteristics of these beams under von Karman spectrum turbulence conditions through numerical simulations based on multiple-phase screen methods. The effects of different inner and outer ring topological charges and varying turbulence intensities on the intensity distribution, beam spreading, and beam wander of DR-PVBs over different propagation distances were examined and compared with double-ring Gaussian vortex beams (DR-GVBs). The simulation results indicate that within a propagation range of 0-500 m, the effective radius of DR-PVBs with different topological charges remains essentially unchanged and stable. For propagation distances exceeding 1000 m, DR-PVBs exhibit superior beam wander characteristics compared to DR-GVBs. Additionally, two occurrences of self-focusing effects were observed during propagation, each enhancing beam stability and reducing the beam spreading and beam wander of the DR-PVBs. This study provides valuable insights for applications of DR-PVBs in optical communication, optical manipulation, and optical measurement. |
