Transverse effects in a passively mode-locked laser (PMLL) are examined. The effect of multiple transverse modes (MTM) on continuous wave PMLLs is giving rise to amplitude instability in the pulse train. For MTM Q-switched PMLLs, we observe the phenomenon of spatiotemporal dynamics that spatial patterns vary with the time.
