Spatial morphology of macroscopic superposition of three-dimensional coherent laser waves in degenerate cavities

Abstract

We employ high-order degenerate laser cavities to analogously investigate the morphology of macroscopic superposition states of three-dimensional coherent waves. The spatial features of macroscopic superposition states are found to exhibit dashed and dotted wave patterns. We evaluate the mode volume to explore the domination of macroscopic superposition states. A large-aperture laser resonator is experimentally implemented to confirm the theoretical results.
