ABSTRACT
In this Letter, we present a novel, to the best of our knowledge, image-based approach analyze mode control ability photonic lantern employed in diode laser beam combining, aiming achieve stable output. The proposed method is founded on theories power flow and coupling validated through experiments. findings demonstrate that analysis combining process highly reliable when main component output light fundamental mode. Moreover, it experimentally demonstrated performance significantly influences loss purity. essence variation-based analysis, key advantage its applicability even situation poor combined stability. experiment only requires collection far-field images characterize model ability, achieving an accuracy greater than 98%.
