The excellent beam quality and heat dissipation of fiber lasers enables efficient and high-power operation for use in manufacturing, medical devices, communications, defense, and sensing. However, the ability to shape a beam with high fidelity could increase the speed and quality of the industrial laser cutting processes, improving its use across these applications. Photonic Lantern Adaptive Spatial Mode Control smart fiber technology enables beam shaping, beam steering, adaptiveoptic compensation, mode-area and power scaling. This technology addresses conventional fiber limitations with mode-control through precompensation and closed-loop feedback. This allows for beam-steering; compensating for thermal, optical, and mechanical disturbances at high power and in the presence of turbulence,and shaping the beam for a variety of applications.
