Abstract

Coupled laser arrays exhibit rich and complex physical properties, making them powerful tools for exploring a wide range of phenomena. They enable efficient ground-state optimization of complex landscapes, solve computational problems, reveal topological defects, study coupled oscillators and their universality classes, investigate classical spin systems and complex networks, enhance imaging through scattering media, suppress speckle noise, generate ultra-high-power laser beams, and produce high-resolution shaped beams. Here, I summarize my PhD research on phase-locking large networks of coupled lasers and controlling spatiotemporal lasing modes for rapid speckle reduction.
