Adaptive Laser Beam Engineering with Coherent Beam Combining for Efficient and Uniform Power Delivery

High-power laser technologies are critical in precision manufacturing, defense, and scientific research, where accurate control over the beam profile is essential. To address this need, we employ coherent beam combining (CBC) through adaptive phase control to precisely craft far-field intensity distributions. We present a comprehensive framework comprising two complementary strategies: (i) dynamic beam shaping through sequential steering, enabling programmable trajectories and arbitrary patterns for versatile energy delivery, and (ii) static shaping via iterative phase optimization, producing target defined profiles such as rings, squares, and triangles. Rapid reconfiguration of beam profiles and steering is achieved through optimized phase-control algorithms. Among the tested methods, a deep-learning-inspired Adagrad optimization approach demonstrated the fastest and most stable convergence, ensuring scalability and robustness. The proposed strategy significantly enhances power delivery efficiency and beam uniformity compared to conventional shaping techniques. This dual-mode CBC framework establishes a versatile and resilient platform for adaptive laser beam control, with transformative potential across industrial manufacturing, materials processing, medical systems, directed-energy applications, and tunable light-field research.
