Twisted array structured light source and its influence by turbulence effects

Year: 2025

Type: article

Abstract: In unstable environments, such as atmospheric turbulence, designing light field structures and phase distributions is crucial for mitigating beam quality degradation. This study constructs an array of superposed twisted Gaussian Schell-model beams with array phases, enabling the beam to self-split and self-stabilize. The array phase not only alters the beam's spectral density distribution but also significantly affects the evolution of its coherence. Under far-field conditions, it enables the beam to split into an array of fields, with the normalized orbital angular momentum flux density reflecting the field distribution and maintaining stability during propagation. This design effectively mitigates the effects of beam spreading and quality degradation caused by turbulence, providing a theoretical basis for high-stability, high-quality light field propagation in complex environments.
