Spatiotemporal extreme events in spatially extended lasers

摘要

We illustrate the study of extreme events in the spatial transverse section of the electric field emitted by a broad-area semiconductor laser with saturable absorber. Spatiotemporal maxima of the field intensity in the three-dimensional space (x,y,t) are identified as events for the statistical analysis. We clearly determine the regions of the parameter space where extreme events are most likely to occur. Furthermore the connection between extreme events and stationary and self-pulsing cavity solitons. occurring in the same system, is investigated.
