Transverse effects on antiphase dynamics in a multi-longitudinal-mode solid-state laser are investigated experimentally. We show a three-dimensional self-organization resulting from the cross saturation dynamics in the longitudinal and transverse directions, in which the intensity noise spectrum of partial output within the beam cross-section possesses the antiphase relaxation oscillation components inherent in multi-longitudinal-mode lasers and the noise spectrum changes along transverse direction, while these antiphase components vanish completely for the entire beam. Modulation dynamics in a multi-transverse-mode laser featuring transverse synchronization and clustering is also demonstrated.
