Abstract

This study investigates real-time dynamics of optical rogue waves in spatiotemporally mode-locked fiber lasers using compressed ultrafast photography. The multimode laser cavity, under relaxed cavity constraints, exhibits long-tailed non-Gaussian intensity distributions. Single-shot spatiotemporal measurements reveal that rogue events produce clean pulses with high-quality beam profiles, undergoing nonlinear spatial transformation due to a power-dependent consistent attractor within the laser cavity.
