Conference Agenda

High-power fiber lasers have become indispensable tools across science, advanced manufacturing, and defense. For decades, power scaling has relied on single- or few-mode fibers to preserve beam quality. However, the very tight optical confinement that enables diffraction-limited performance also enhances nonlinear effects, imposing fundamental limits on further power scaling.

In this talk, I will present a different approach: embracing highly multimode fiber amplifiers as a pathway toward mitigating nonlinearities while enabling substantially higher output power. While multimode fibers are traditionally associated with complex and unstable spatial dynamics, we demonstrate that this complexity can be harnessed rather than avoided. By applying spatial wavefront shaping to the input field, we achieve deterministic control over both the spatial profile and the polarization state of the amplified beam.

This strategy enables high-power, high-efficiency, narrow-linewidth operation in a highly multimode platform, challenging the conventional paradigm that beam quality and multimode propagation are incompatible. The results open new opportunities for scalable coherent beam combining, large-scale interferometry, and remote sensing, and suggest a new direction for the future of high-power fiber laser technology.
