Abstract: In the current pursuit of extreme laser efficiency in fields such as optical communication, how can we achieve optimal transmission effects with minimal energy consumption? The angle has emerged as a crucial key in this endeavor. This paper aims to investigate the impact of inter-ring angles on the transmission efficiency of dual-ring Airyprime-Gaussian beam array (DAPGBA), specifically analyzing the beam's auto-focusing capability, power, and auto-focusing efficiency, with experimental validation conducted. The results indicate that variations in angles do not significantly affect the transmission process of the array beams; rather, they determine the characteristics of the initial plane intensity distribution. When the initial planar local light intensity exhibits monopole convergence, the auto-focusing capability reaches its minimum. Conversely, when the local light intensity demonstrates multipole balance, the auto-focusing capability attains its maximum value. This differentiation manifests a nonlinear variation in the intensity distribution characterized by an ordered-to-chaotic transition. To facilitate a more effective measurement of transmission efficiency, a concept of auto-focusing efficiency is introduced. In scenarios where perfect double auto-focusing is achieved, it was observed that rotating the outer ring results in variations in the initial plane power, auto-focusing capability, and efficiency of the DAPGBA as a function of the rotation angle. Through the selection of angular parameters, we achieved nonlinear geometric regulation of the initial light intensity distribution in DAPGBA, thereby optimizing its transmission efficiency. When N = 8, the auto-focusing capability of 13.50 is obtained with the auto-focusing efficiency of 35.00 %. When N = 12, the auto-focusing capability reaches 17.30, with the auto-focusing efficiency up to 36.02 %. When N = 16, the auto-focusing capability of 21.60 is achieved, while the auto-focusing efficiency climbs to 43.15 %, and the power increases within 3.50 % compared with the minimum value. This approach provides a novel direction for improving multi-ring arrays, greatly enhancing the potential applications of such array beams in cutting-edge fields such as laser medicine, optical communication, lidar, and quantum optics.
